Trying to find a wiring diagram for the wires that come up to the engine compartment from the transmission any help would be appreciated thanks I've got three wires I'm trying to figure out where they go
.. there's no connector to them and looks like they've been ripped off of whatever they were connected to
There was a blue one , i i figured that went to knock sensor. That wire comes from a harness on the passenger side where i have some ground wires going to the rear of the head. The 3 wires in question come from a harness on the driverside and up into engine comp.from way of trans. Are there ground wires that goto rear of right head also. ? 1 is solid black, 1 is black/white and 1 is black/red or brown
When we put the reman in and turned key on for first time my rpm and speed guages were pegged out. All other guages were fine. Cranked it. Rpm started working as it should, speed was still tapping out at 💯. Went for test drive speedo bounced around then started working . Upgraded to mpfi and blazer has hardly no power .
Of the 13 wires coming off of the transmission there is a light blue and a dark blue wire. They both go to the vehicle control module by the right front of the engine compartment on connector C3 with no splices or in line connectors on the way. They are for the pressure solenoid and one of the temp sensors respectively. There are no external grounds to the frame for the transmission wiring.
The speedo problem could be the speed sensor or wiring which is at the rear of the trans and has a LT grn/blk and ppl/wht wires. I forgot about the speed sensor so there are 15 wires to the trans not 13. The speed sensor wires also make a straight shot to the VCM in the engine compartment on C1,
Mystery wires ...please help
