Specifically pin 1 but if you have the rest that would be great too.

On L8's it's the earth for the Ignition Adjust and commoned with a ground near the battery.

Thank you much! Strangely enough it matches exactly what I have from tracing out my harness, so thats good news. It also filled in a couple of blanks for me..for example, what is "octane adjust" (pins 13 and 14) and what is "Electronic control loom" (pin 8)

thanks !

 

As to be verifieyed but on the P8 I guess the Octane adjustments pins are used to reset the Keep Alive Memory

Hello everyone

Also remember if you have pats system in your escort some of the pin outs might be switch around abit, atleast they are on the small turbo.

 

Are there harnasses for the loom/ ECU of a big turbo Escos available? I can't find any.

 

does any one have a pinout for 03 focus zetec s with map sesonr
