Exposed Posted December 2, 2015 Share Posted December 2, 2015 Hi everyone, I recently purchased a '72 240z and was able to grab a 1jz out of a soarer with an automatic transmission localy for relatively cheap. With that being said I'll be posting pictures and asking questions as time goes on. So what better time to ask than the present. Pictures will follow shortly. Has anyone been able to use an automatic transmission on there 240 1jz build, and if so how did you make the connection with the wiring harness? I was hoping to get a complete wiring harness but can't find a supplier who makes them for automatic transmissions. Quote Link to comment Share on other sites More sharing options...
seattlejester Posted December 2, 2015 Share Posted December 2, 2015 Welcome to the forum. Literally right above your post in the sticky is an excellent outline of someone fitting an automatic in their 240z so someone definitely has done it. I would imagine you just keep the plugs on the transmission and run the stock ecu. You would have to suss out the superfluous items, but to my knowledge a toyota wiring harness is pretty simple if you have it complete, just need the power, ground, and the fuel out. I can't remember if the 1jz was advanced enough to need a wheel speed sensor to determine which gear to shift to. Quote Link to comment Share on other sites More sharing options...
madman88 Posted December 3, 2015 Share Posted December 3, 2015 If a complete wiring harness is what you are looking for you could always get in touch with wring specialties I have heard quite a few times of them custom building harnesses for what their customers want.

Exposed Posted December 3, 2015 Author Share Posted December 3, 2015 Thanks for the responses, I've got in contact with wiring specialties already they said they don't make them for auto's. Quote Link to comment Share on other sites More sharing options...
Exposed Posted December 6, 2015 Author Share Posted December 6, 2015 Finally got around to taking some pictures. I'll post some pictures of the cut wires on the harness, any info on where they go would be awesome. In the mean time i guess I'll be going through other forums/ build threads and seeing if anyone is in the same boat. Quote Link to comment Share on other sites More sharing options...
Drift Boss Posted December 7, 2015 Share Posted December 7, 2015 Yeah. I would get a new harness from wiring specialties. I run one in my 2jzgte swapped 280z. Quote Link to comment Share on other sites More sharing options...
dexter72 Posted December 7, 2015 Share Posted December 7, 2015 I would try joining the Club Lexus forum, they may be able to help with some wiring info. Diagrams, Possible harness. Quote Link to comment Share on other sites More sharing options...
Exposed Posted December 8, 2015 Author Share Posted December 8, 2015 @DriftBoss, they dont sell any for an automatic and I'd prefer not to mess around with trying to swap something like that from a manual to automatic. I was going to try DrTweak and see if he would do it. On a side note, I was checking out your build and saw you brought your drive shaft to a shop. Did they just extend it for you or did the splines need to be swapped out for something else? @dexter72, I've gathered a bunch of diagrams from there thanks for the suggestion though. I was able to find a cheap used engine bay wiring harness for an automatic on ebay for a couple hundred so i snatched that up quickly. When wiring your interior (dash, and all that other fun stuff) is there a main connection typically from your battery to your fuse box then from your fuse box to the other stuff or does it get routed from one of the existing wires from the ecu connection? The good news is I'm repairing some panels on the existing car where there was rust and I'll be doing a mock up for the motor and transmission mount within the next couple of days.

Exposed Posted December 16, 2015 Author Share Posted December 16, 2015 Found some time over the weekend to drop the engine and transmission into the car. I had be reading up on different mounts that were for sale (not many I might add) that wouldn't break the bank. I ended up fabricating my motor and transmission mounts and got them welded up. Just a heads up to someone planning a swap like this, it isn't to hard to make your own mounts and it's really cheap even if you have to pay a professional welder to weld everything up for you. Placed an order on a radiator and an intercooler and now its a waiting game. Quote Link to comment Share on other sites More sharing options...
Drift Boss Posted December 18, 2015 Share Posted December 18, 2015 Plus the cxracing engine mounts, I ended up re welding anyway. Just don't bolt mounts threw frame, I seen this go very badly. Quote Link to comment Share on other sites More sharing options...
Exposed Posted January 5, 2016 Author Share Posted January 5, 2016 So will I was waiting for the new parts I had order I end up pulling my dash. Bad news is the dash is cracked, luckily its only one small one so I might just reupholster it. I'm currently planning on switching up the existing gauges. The speedo and tach is 5" and the other guages are 2 5/8" or 52mm if I'm not mistaken. I'm not set on any particular brand of gauges as of right now but was thinking of getting something with a dial for my speedo and tach and digital for my other gauges, was thinking of getting something with a white or purple light to it. Does anyone have any recommendations or reviews on products they've used before? Came in to work today to find my intercooler has finally arrived, the core size is 12.5"x 22"x 3.5". Now im just waiting on my rad and fan which should be coming in tomorrow morning. Quote Link to comment Share on other sites More sharing options...
Greeko Posted January 31, 2016 Share Posted January 31, 2016 52mm is closer to 2-1/16 if I'm not mistaken Quote Link to comment Share on other sites More sharing options...
Greeko Posted January 31, 2016 Share Posted January 31, 2016 Where did you get your intercooler, rad fan from? Quote Link to comment Share on other sites More sharing options...
Exposed Posted February 1, 2016 Author Share Posted February 1, 2016 @Greeko, Thanks, and I ended up grabbing the intercooler, rad and fan locally. I'll have to grab the tubing for the intercooler from somewhere else though as no one here seems to carry anything. I found some time to mount things up recently and tested out some paint in the engine bay. Quote Link to comment Share on other sites More sharing options...
ShaggyZ Posted February 2, 2016 Share Posted February 2, 2016 Plus the cxracing engine mounts, I ended up re welding anyway. Just don't bolt mounts threw frame, I seen this go very badly. Tell me more! Seriously. Quote Link to comment Share on other sites More sharing options...
Exposed Posted February 5, 2016 Author Share Posted February 5, 2016 Managed to grab some seats locally for $25 a piece. The overall shape of them is ok the drivers seat does have a small tear about 1" big. I managed to get most of my wiring hooked up just need to know where some plugs go. Anyone have any ideas on what to do for a fuse box and if I'll be needing an interior and exterior one? The 240 never had one when it was purchased.

seattlejester Posted February 5, 2016 Share Posted February 5, 2016 I made my own using the cheaper 10/12 fuse box and associated relays and that really didn't last. I found leash electronics makes pretty nice fuse/relay boxes. Haven't had any trouble with mine and it's running my megasquirt, fuel pump, coils and such.

Nelsonian Posted February 8, 2016 Share Posted February 8, 2016 Interested in that Mishimoto radiator you have there Exposed. Custom work done or another model application ? Quote Link to comment Share on other sites More sharing options...
Exposed Posted February 8, 2016 Author Share Posted February 8, 2016 model specific (corolla), I ended up with about 1/4" gap on either side of it and the height was bang on. I can take some pictures if you'd like or can try finding you a part number. Quote Link to comment Share on other sites More sharing options...
