Re: Identify these wires/connectors???

the ones with the eyelets are ground straps, either to the back of the cylinder head ot ro the firewall.

what colors are on the gray conector?

The blue wire goes to nothing on mine, it was factory taped into the wire loom. You can see it here

I remember there was some issue when I did ground it. Don't remember what it was but I taped it back into the loom. m

Re: Identify these wires/connectors???

Thanks for the info Twin_Turbo! So the blue one is an "extra" the black one is a ground. Here is a a better pic of the plug in question. It comes out of the same loom as the black ground wire.


Wires are red and white and plug into a plug. (if that helps)
