You guys sounded like this was an option. All you have to do is wire the MAP ->AFC->ECU? So you are controlling the MAP voltage with the AFC, then sending the signal to the ECU?

Can I get a pinout on JZX90 IH1 and IH2 connector I have pictured up top? If I can get these wires decoded, I can wire to the dash, and finally to the ECU so this friggin thing will shift! I have JZZ30, Us, and JDM, and I have a ton of JZA70, but no JZX90 stuff.

Wow, 21 pages there's a lot of GM V8 Talk for a Toyota forum... Power isn't everything, and if you think any V8 sounds better than a boosted inline 6, then go buy a Camaro. NOW AR5 and AY6 into JZ engines, can we get a little Cliff's Notes action, or is everyone too concerned with something...

GReddy BCC? Is that a MAP sensor? I was asking if the GM MAP worked at all?

Sooper Bumper!!11! Any more info on this?

This is great stuff, and answered pretty much all my questions. Thanks!

Do IK and IJ change at all between supra and sc300? Probably not, but the chaser IJ and IK look almost the same, except the they have a little more meat on the outsides and doesnt quite fit in the socket. The pin arrangement is the same, but the plugs are wider. pm me with a paypal or whatnot...

My 1jz runs as well. I got the engine harness and ECU wired up. The only thing I am missing is: Auto Trans plug wired in, Dash, tach, speedo, etc. There is only one plug of the jzx90 harness that plugs into the sc300 body harness, and I had to repin it. The Square gray one w/ b/r , b/y that...

I just wanted to list what plugs do what for myself and other people searching. Yes IJ and IK are the plugs I wanted to decode. Is the white IK the Dash or the Gray IK? Which one is the trans plug? Basically, is the Chaser harness wire colors and plugs the same as soarer?

I need to find out what plugs do what on the ECU side of the chaser harness. ECU pinout and wire colors have been covered. I wanna know what plug is TRAC, Dash, Trans, etc. Then I will make a swap post with these details in mind.

I am in the process of wiring in a JZX90 1jz into my SC300. The cars are different, but the premise is the same. There needs to be thorough documentation of the jzx81 jzx90 chaser 1jz. I will shed a little light on Harness Plug orientation. ECU PLUGS (Omitting the 16 pin with TRAC, Fuel...

I need this info as well, currently doing a sc300 w/ jzx90 chaser 1jzgte. I think the fat plugs are for powering the inj, coil, ecu. The skinny 2 row plugs are for the dash lights, and tach, spd, etc. which is which?

V-band and AN. Always a good mix.:icon_bigg

Clean setup! Oh and Old skool' Delta gate FTW!

I am a part of 'tuners, although I don't visit it much anymore, waaay too many no0bs. It took me 2 years to build my car correctly, and now I don't want it since I moved from Maine to VA beach. Don't exactly need to worry about snow anymore. I have been building cars in general for 10+...

Car looks good... I have to sell this gaWd dam Galant already! http://www.supramania.com/forums/showthread.php?t=47562

Yeah, I'm looking to trade or sell my built Galant VR4 to finance the project. I really like the white 90-91 era MKIII Hardtop. Or any hardtop for that matter. I've been on the search for weeks, lol. I hope to take my years of experience in other makes and areas(7plus years in...

Wow, True JDM indeed.:love: Incredible job!

Thanks guys! Seems really warm around here. To be honest, DSM guys are generally Self-indulged pricks! Can't wait to start doing the Supra thing!
