Knock sensor wire color?
This applies to an 87 TPI 5.7 auto.
There are 2 wires with same pigtails, one white one dark blue.
Which one goes to the knock sensor?

Other one is the fan switch wire. Knock sensor the lower one in the block, fan switch is the higher one in the head.

Re: Knock sensor wire color?
The color of the plastic on the sensors almost matches the wire colorsm (light to light, dark to dark). Little thing I picked up and remembered when bringing a basket-cast 87 GTA back from the dead. Once I realized it, I thought "oh, I guess GM did it that way on purpose."
