Hey guys, i have a question regarding the colors of the wiring diagram. The knock sensor shows GY label, is that a Gray Wire? Also is L for Blue?

 

Correct

 

Damn, so my next question is - on all of the manuals available online, the wiring diagrams show Engine Harness but then underneath that in paranthesis it says 'Turbo W/ ABS'.

Are wiring diagrams different for NA models?

 

There will be differences between the NA harness and the TII harness. Different components are used and the wiring is different, especially the pinout on several things.

 

I figured as much. Annoyingly this diagram is from an 88. I have an 87. And it looks like there are small variations even between 87 to 88 NA models.

 

There was a change mid 1987 that can be identified by VIN (serial number -7601 was the break).

 

 

I wonder what a Natural color looks like.
