Hello, what exactly do you need? An internal trans wiring part? External harness off the transmission?

Ask Your Own Mercury Question
Customer reply replied 1 year ago
An External harness off the transmission.
Customer reply replied 1 year ago
The connector that I robbed from a similar wiring harness has 9 wires connected to it --which I spliced into my wiring harness, replacing the burned up connector. Six of the nine wires had unique colors/stripes on them and were easy to accurately splice. The three remaining wires were all solid red and a thicker gauge wire. It was hard to be sure on these wires if I spliced to the exact red wire in my wiring harness. (Does it matter?)
Customer reply replied 1 year ago
Should my next step be to completely test the wiring harness using a schematic diagram, or would it be easier to get another piece of the wiring harness which matches the one I have?
Mercury Mechanic: HDGENE, ASE Certified Technician replied 1 year ago

Yes it does matter, this is the transmission bulkhead main connector?

Customer reply replied 1 year ago
I don't know. when the splicing didn't seem to solve the problem, my mechanic suggested getting an electronic component from a wrecking yard that was blue, rectangular, a little bigger than a deck of cards, thinking that it might have been damaged by a voltage/amperage surge along the way. The part I brought back actually made the car run worse when it was installed.
Mercury Mechanic: HDGENE, ASE Certified Technician replied 1 year ago

Ok Im confused. Do you need to perform a wiring repair or change some sort of other part?

Ask Your Own Mercury Question
Customer reply replied 1 year ago
I need to know if there is a source for replacing the section of the wiring harness I have, which seems to be the problem. If no source exists, I will need to know where I can get get a schematic for the piece I have so that I can check it, wire by wire, for continuity/resistance I guess.
Mercury Mechanic: HDGENE, ASE Certified Technician replied 1 year ago

I can provide a wiring schematic, but I need to know what section you need to repair

Ask Your Own Mercury Question
Customer reply replied 1 year ago
I will go to the transmission shop that has the car and ask them to remove the piece of the harness. Then I can give you a part number or at least the description that they give me as to which section it is. Is there more than one section that attaches to the transmission?
Mercury Mechanic: HDGENE, ASE Certified Technician replied 1 year ago

Very good. For the transmission controls, no. There are some external sensors and controls. So I need more specific information.

Do you need more help with this concern?

Mercury Mechanic: HDGENE, ASE Certified Technician replied 1 year ago

Ok I see what you are working with and where you tried to repair the transmission bulkhead connector. Are you having an issue with matching up the wiring for the bulkhead to be wired correctly?

Ask Your Own Mercury Question
Customer reply replied 1 year ago
I think I may have made an error splicing the 3 red wires onto the connector.
Customer reply replied 1 year ago
I think I need the wiring schematic so that I can trace the three red wires to their proper connection in one of the other plugs in this harness
