Unplugged wire-can't identify - 4/13/2008 12:04:44 PM    Doran Posts: 19 Joined: 3/23/2008 From: Bedford, Tx Status: offline Trying to figure out what this wire is, I have a picture of it, the wire runs alongside the main harness but since it has a retangular clip on it I don't think it goes to the one open spot on the main harness, as identified in the photo with X. The wire circled in white is the one I'm trying to figure out, any ideas where this hooks up? The wire appears to be a dark color, possibly black, in person tho it looks a little green in the photo. I've checked the area and found nowhere to plug it in, no open terminals anywhere around there. Any help is greatly appreciated.

Swartlkk, I have no clue, what does that look like? hahaha I'll look it up in my manual, maybe it'll be in there. That would explain why it takes so long to start on cold starts I guess huh? Or at least, could be one possibility. (in reply to swartlkk) Post #: 4

You could try supplying +12V to it using a fused jumper wire from the battery and seeing what happens.  If you hear your pump kick on, then it is the prime connector. _____________________________ Kyle- My Restoration Projects Please Do Not PM for Tech Help (in reply to Doran) Post #: 5
