First off, I just want to say thanks and show my appreciation to those who have posted on this thread with answers. It has really helped. Thanks again.

 

Okay, I cant find anything on the wiper "Amp assy INT. wiper". I just need to know what wire does what so I can finish installing the painless wiring harness. If anyone know or can direct me in a better path. Please let me know. Thank you in advance.

hey i'm new to this forum and i have a 72 240z. I decided to go with a not so painless wiring harness 18 circuit and can't seem to figure out where a few wires go. i've got most of the answers i was looking for on this thread but i wanted to know if anyone has a picture of the wiring between the voltage regulator and the alternator. original wires or painless wires. this is the only thing left for me and i can't seem to get this down right. i don't know what wires really go to the voltage regulator. diving me crazy.

I took out the old alt, voltage regulator, and am swapping in a GM 12si unit. Search Gm 12si and there are a couple threads on the subject and other Gm altenators.

 

I found the one by hizandherz very helpful. Im having a friend and electrician wire mine but i purchased the EZ 21 circuit harness and it had an altenator circuit in the fuze box, forgoing the need for the fusible links and the altenator has a voltage regulator already built in.

 

The Ez wiring harness I have is Gm based to the altenator wired right up. When Its all finished Ill try to put up pics in a seperate thread.

Anyone having any issues with fuses tripping on thier painless harnesses?

 

Currently my turnsignal fuse will last about 10 minutes, and when it goes, I loose the dash lights, guages stop working, turn signals stop, and brakes stop. I don't recall having this issue in the past, but to be honest, I just got the car back home after having it in storage for a year or so.

 

Any thoughts? I think I might have too much of a load on that circuit and didn't realize I had everything wired up on the same one. But the wires are labled, so that doesn't make a lot of sense, but this was my first wiring job...

 

Thanks.

Sorry to ask such a stupid question but...

On the combo switch, are the wires on either side of that 9 pin plug the same colors?

 

I dont have the harness side of it! Havent been able to find one at a yard either :\

 

I don't think so. Mine are all green (I'm not sure where i got the plug from).

I'm missing something pretty critical. I don't have the wiring harness side of the 9 pin plug that powers the wipers. I can't find a plug at any of the scrap yards around here, and the couple of z shops around town want $buttload to supply me with one.

 

Since the Painless sticky's pinout diagram is for painless harness to the plug, and I don't have the plug, I'm screwed! I have no idea which wire on the one side of the plug matches up to which wire on the other side of the plug. Can somebody make me a pinout of the 9 pin connector underneath the column? I need to know which color on one side corresponds to which color on the other side.

 

Or better yet, if there's anyone in the Seattle area willing to let me sit in their drivers seat with a pad and a pen, I'd appreciate that too.

 

Thanks everyone, and if you're in Seattle, gimme a call at 425-772-1481.

The colors should match from one side of the connector to the other. There may be a few instances where that is not the case but I've not run into that.

So not to bring up this from the dead... but I recently got a 71 240z that needed to be rewired! Bought a EZ 12 mini kit and having issues with the wipers? Mine only comes with 1 blue wire that says wiper power? not sure how to hook that up and still have my 2 speeds? Am I suppose to add extra wire to wire the switch to the motor? Am I suppose to reuse part of the old harness? Why is there only 1 wiper power cable and nothing else?

question about painless harness to a 71 240z 4 wire tach... I'm confused about how to hook this up- I have a purple wire coming from the coil and a red white power wire to supply power to the guages-

 

the tach has a loop of wire white with black and white with red (same wire loops through a coil) a yellow/ red and a black...

 

assuming black is ground, how do I hook this up? I called painless today and they were like uh...get a chevy dude...

 

any help appreciated. thanks for this thread!

73' and up combo switch.......

10 ga Black.......................Ground wire for wipers, washer fluid wipe, Headlight Hi/lo beam (over to the turn signal switch)

White/red..........................Headlight power Input (+)

Red...................................Headlight power output (+)

 

Green/white.......................Parking light power in from fuse box (+)

Green/blue........................Parking light power out from switch (+)

 

Blue..................................Washer fluid input.....................................\\\

Blue/red............................Washer fluid output------------------------------->> button on end of combo switch

Blue/white.........................wipe while pressing the washer button......///

 

Yellow/green.....................Wiper park (-) has to be grounded for wiper to operate (first click)

Blue/yellow........................Wiper intermittent wiper timer (not active unless yellow/green is grounded.

Yellow/black......................Wiper Low speed (-)

Red/blue...........................wiper High Speed (-)

70' to 73' Turn signal switch
Solid red or black single wire that connects to the combo switch.........Headlight Hi/lo beam input ground wire.

Red/white...............................Headlight High beam negative wire

Red/yellow..............................Headlight Low beam Negative wire

 

Green....................................Turn signal input from 2-pin flasher

Green/yellow..........................Brake light input wire (+) from the brake pedal switch

 

Green/black...........................Front Right turn signal output

White/red...............................Rear Right brake / turn signal output

Green/red..............................Front Left turn signal signal output

White/black............................Rear Left brake / turn signal output

 

74' to 78' Turn signal switch

Same as 70' to 73' but no Green/yellow brake input and no front (green/red and green/black) turn signal wires. 

74' and up have separate brake and turn signals in the rear, which is why the 70' to 73' have 6-wire switches, versus the 3-wire switches on the 74' and up.

 

The 74' and up brake wire goes directly to the rear brake lights. Not through the turn signal switch

Yes a Ford guy found this! But I'm in need of some help on a 7/ 70 240Z. I'm in the process of installing the Painless 18 circuit 10102 for a friend. He wants to keep the original Tach, but can't seem to find how to wire it up?  I found this AWESOME website and it has helped me Tremendously on this project! 

Thanks for any help in advance,

Chris
