does anyone know step by step on how to wire up 87 t2 ecu on a 85 glsse,need to now the color of the wire to power it up

 

It's been too long for me since I put a TII in the Porsche to remember. But check the Factory Service Manual available in PDF on this site. I went by the pin numbers and not the color of the wire. You really only need to hook up a few wires to make it run. 12v switched, ground, and a couple others I can't remember.

Again, with the help of the FSM and carefully counting which pin, it was fairly easy.

 

still do not what wire power the ecu up

 

On a '89 Turbo ECU

1A is 12 volt continuous

1B 12 volt switched

The whole schematic is on page F 2-8 of the Factory Service Manual. The manual is available in PDF on this site. Download the manual, print F 2-8, study it and it will all become rather obvious. It explains all 64 pins in the ECU.

 

the 87 ecu does not have 64 pins it has 52 and look at this https://www.nopistons.com/forums/ind...howtopic=13587 you can see in the plug the wire not need ,and go here and go to pag 4b-33 you can see the pulgs to the 87 ecu http://www.wankel.net/%7Ekrwright/files/ma...ssion_cntrl.pdf. you can see it saids 3j is the power and 3I GO TO THE MAIN RELAY, WHAT DO YOU THINK ,

 

how do i check the ground on the injector..they have power

 

Do a continuity test.
