Mudge Posted March 29, 2003 Share Posted March 29, 2003 Someone with an 80s ZXT car, maybe even ZX wiring is similar... I am trying to figure out which battery posts go where. One of them is bare, with what looks like a ground connection and then connects to something else, maybe the starter? Then there is another terminal set with a small box on one end, with red green and black wires, which is a connection spot for about 3 different connectors on the harness. I am assuming this goes to the positive lead on the battery but am not sure, everything is black as far as terminal covers so nothing is obvious as a modern car would be, and should have been then. There is no red on any of the posts in other words. Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 30, 2003 Author Share Posted March 30, 2003 I figured out which is which, black with yellow stripe is ground. Now, anyone know where they go to on the chassis/engine? Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 30, 2003 Author Share Posted March 30, 2003 Does anyone have a picture of what the wiring to the starter solenoid looks like? So close, yet so damn far. Quote Link to comment Share on other sites More sharing options...
Len Posted March 30, 2003 Share Posted March 30, 2003 Mudge The neg. ground runs directly to a bolt on my frame below battery box. then grounds the engine. positive side runs to starter. Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 30, 2003 Author Share Posted March 30, 2003 Figured ground would ground somewhere, but there are two end terminals for bolt down. I will keep looking. Positive runs to starter, any idea which side or does it not matter? Do you have a diagram of the alternator side or picture? After this I'm about home free. I appear to be missing one plug (prong) that goes into the alt which is mostly what I'm worried about, I think the rest of the wiring is correct but not positive, and of course I'd rather not fry something. I should have taken pix before hand, somehow didn't occur to me. Quote Link to comment Share on other sites More sharing options...
Len Posted March 31, 2003 Share Posted March 31, 2003 I would check for you except currently I don't have access to my car! I will look hopefully tomarrow and let you know. Quote Link to comment Share on other sites More sharing options...

Mudge Posted March 31, 2003 Author Share Posted March 31, 2003 Thanks! Ignition may be a sticking point (I had GM HEI before), fill the trans, wire & mount the pump (half way done), cross over ignition hookup to new harness, hookup the linkage (may be missing a peice or two), fill rad with water and bleed the system, and then start chasing down all these -open- vacuum lines. There is also something else which looks like an adjustable vacuum thing or something, from near the AFM area and I'm not sure what it is, but I'll find out eventually I suppose.

Mudge Posted March 31, 2003 Author Share Posted March 31, 2003 I get spark when turning the key towards off, but I do not get a constant spark when I am turning it over. I unfortunately did not look at how the coil was wired in the other car, nor did I label it because it looked obvious (mistake). I am fairly certain I am using the correct part of the harness (somewhat tough to get wrong), but the complete coil wiring is a myster to me. There is a 2 prong connector below the coil which is shorted to itself, yet has both the ground and positive coil wire going to it, so this I assume is the resistor? On the distributor there is a 4 lead connection, that is hooked up to the harness. There is also however a single prong connection and I dont know what its for or where it goes, it is at the base of the dis of course. Other than the coil connection to dis, and spark plug connections that is the only remaining one without a home. Unfortunately on the same part of the harness there are two connectors with no home, I am thinking they may be for the water pump, one is a male "round-spade" type connection, the other has no connector on it (broken). The broken wire was yellow and I think the male plug was black but I am braindead right now. So basically the distributor and coil are in question for me right now, the fuel pump works. I suppose its also possible that the injectors are dead, dont know. I think the rest of the wiring is ok but I will check tomorow of course, spent a couple hours trying to figure out the dis/coil thing and just no go. If anyone has pictures of wiring in these areas or wiring diagrams that would be great, I will go through the book again to see if I can get some kind of understanding from it. This is an 82 setup, so the "crank sensor" is in the dis. Quote Link to comment Share on other sites More sharing options...

Mudge Posted March 31, 2003 Author Share Posted March 31, 2003 ((((((((((((((((((jump the positive side of the coil with a wire to battery, works))))))) Ok, I tried that one too with a relay, so perhaps my problem is something else (maybe computer not getting juice). ((((sounds like water temp, if its a bullet connector, but that would be from 240z harness right?)_ Actually they both use similar connectors, then again I had an N42 on the 240Z so maybe that would be why. I have another N42 thermo housing with the connections on it and I forget how they are different, but only in that there are I believe two extra connections, like the water temp sender appears in the thermo housing on the N42 where the P90 looks to be between 5/6 cylinders(?) I figured it would just run rich without the temp sensor hooked up, kind of like an open loop on a modern car, but I will try to hook that stuff up also. There is a male bullet and female bullet on the thermo housing currently though, I'm not sure if what goes there comes off the coil harness or if I didnt route something I should have. (((((((((((((((((coil transistor probably not wired up if everything else looks like its getting power, it needs key on power to get voltage to the coil, if you want it to start fast, you can hotwire to the battery to get it to kick over, if it does, then thats your dilema.)))))))))) Oooooooooook, there is a module that looks similar to the GM HEI thing except its all metal, I think its 3 or 4 pronged, that is probably it. I will check on that! ((((((((the only two that really matter are the one with -| plug and the thick ten guage that goes to battery, you may have to do some more work since i think your car was external regulator before.)))))))))) Ok, the -| plug is hooked up from the NEW harness but I did not splice in the old one, and that was popping in my head this morning. Its a tight reach there so thats why I didn't cut things up, I will setup a spade hookup so I can branch them together and hook them up. There is another connector in the same region of harness about 6" closer to the firewall that has the same darn connector, and I dont know what its for, it has black shielding but from the rest of the wiring I think I am using the correct one. Thanks for the help dude, I thought you were in Vegas this week. I do have the starter correct, it cranks great, just wont fire, maybe its my FI. The set of connectors coming off the + battery term is missing one 2 prong male connection to it and I dont see any two prong males on the harness like this, it would be a | | pattern which is also abnormal from the other -| type stuff. This is the box with the green and red wires, which I think is what you are calling a fusible link (dont even know what that is, I expected a fuse...) Anywho, yeah it seems close, thats why I stayed up later to try and get it right, just no go, hopefully tonight. I will definately call if I can't get something going.

Mudge Posted March 31, 2003 Author Share Posted March 31, 2003 ((((((((((((that sounds like ground, with connections to the small fusible link, the rectangle box, and the efi relay Oh crud, that is coming off the + terminal right now, from the length of the cable I thought it was positive, plus the red and green wires, damn Nizzan wiring. The one I'm using for - on the battery right now is black with a yellow stripe, which on the rest of the harness I thought was ground. I'll take a closer look and swap those I guess, since you say use the stock + it sounds like I have these backwards, oops. Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 31, 2003 Author Share Posted March 31, 2003 Oh Len, the ID of the exaust (pipe after the downpipe) is 2 3/8", so I guess the OD of the slip on cat is 2 1/4"ish, obviously the cat is not being used... Quote Link to comment Share on other sites More sharing options...
fl327 Posted March 31, 2003 Share Posted March 31, 2003 if you are using the ground from the zxt harness it would be that one with the b/yellow combo goin on. all metal gm module looking thing is the transistor if its connected to the coil bracket. head temp sensor is on the side of the head, not by the therm housing, nothing there will make you run rich. yes, i just got back in from vegas last night about 6pm, it was a blast, except getting took minimum 14 stiff drinks (no beers, some comps, small bottle hennesey in my back pocket) a day starting at 1pm, two buffet meals a day( gotta do it, especially when youre rocking Eggs, bacon, porkchops, and calimari steaks for breakfast, with primerib and hash browns YEAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH), rolling with the baddest crew there is-my crew baby! the last day we got sick of getting broke by the tables, so we decided to throw the rest of our money away at the strip club, i got the thangs rubbed in my face for hours man oh man oh man. sin city is right Quote Link to comment Share on other sites More sharing options...
