Here's something to think about if you don't want code 42 and the engine damage light turned on and I can't remember it being addressed earlier. You need the MKIV odometer/tripmeter wired in between ecu and speedometer.
Is this Supra specific? I have the Aristo swap running and I have no codes or CEL ..Here's something to think about if you don't want code 42 and the engine damage light turned on and I can't remember it being addressed earlier.

Ah well if you don't have ABS then it won't help youYepp me to, have a MKIV electric speedo in the MKIII combination meter. Replacing speedo gear??? I dont have ABS.
I have 2JZ and V160 in MKIII and never had Code 42. Thats on a JDM setup. Speedo was wired to Apexi RSM - may have had something go back to ECU. Cant remember now! Definitely didn't have odometer thoughIt is 2jz-gte with v-160 specific. I'm not sure if there are any differencies between Europe, US, Japan Supras or auto. The odometer/tripmeter takes the speedsignal from the speedsensor on the gear box and transforms it and sends a signal to the ECU. Without this signal you get code 42 and CEL. Have you wired everything correct?
Hi All,IBoughtASupra is correct, and the system will work fine that way. It's the way it was designed to work with the 7M. Like the pinout says, connect pin 13 of B1 to pin 34 of E10.
However, the 2JZ ECU has the ability to deactivate the A/C clutch under full throttle conditions so that no power is parasitically being drawn off buy the A/C system at that time. And there is a way to wire that feature in to the MKIII, but I wanted to test it first, to be sure, before I put the information out there. Unless somebody else has done it and can comment on it.
Until then I would just connect it the way shown in the pinout above.
