where are you guys getting wireing diagrams from? is there a 7M to toyota pickup diagram out there? wheres the B1 connector? i spent the past 2hrs looking over an 88 supra 7mge diagram, but i dont have a plug number diagram.
im putting a 1988 7mge in my 86 runner.
I used a haynes guide when I did mine. It does not list the plug names but shows the correct wire colors. With this and a guide for your year truck you should be able to splice things together as the two efi systems are very similar. Which wires are you wondering about? You should only need 4-6 to fire the engine.
I looked on supracharged.com and the b1 is the big square yellow connector. It will have the thicker gauge wires in the center with the thinner ones around the outside. This is were the supra engine harness would receive power from the supra ignition. This will have a thick black with blue stripe which is the starter. As long as the starter is grounded applying power to this will turn the motor. There is also a thick black/orange which suplies power to injecters and coil.
Splice switch power to these and a couple others to the wires coming from your trucks ignition. All the wires you need should be down were your old 22r engine harness went to the ecu. When you wire the starter make sure you wire it to start power and not from the on position as this will be bad for the starter.
