Need a little wiring wisdom. Has anyone been able to eliminate the wide open throttle relay by patching the wires together?

I have just finished rebuilding my AC and I noticed the casing on the wires to this relay's connection are toast. My heater core went out last Fall so while I was in there. . . new evaporator. Last week was the new accumulator with line and low pressure cutout switch, suction line, discharge line, cleaned compressor, condensor and pulled vacuum before adding new 134a man has this been a learning experience.

I've tried black tape but still my AC cuts out when I'm cruising down the road feeling icy cold. It's really annoying because I have to flip it off and on a couple of times to get it to come back and just about the time it's good and cold it may do it again. It's not my low pressure switch, it's new, or low freon because gauge has it right on the money. Everything works great except for this little connection. Also am able to wiggle the connection and get the compressor to kick in to confirm the culprit. It's also fine while it is parked. It blows 42 degrees at vents while at idle in 100 degree heat in garage for 20 minutes without a problem.

I am trying to find the connection and a stretch of wire at a junk yard since Ford doesn't sell this but wrecks are gettin' hard to come by. Any chance I could solder a new stretch of wire to the old connection and splice in the new wire?

Thanks for the help.

I don't think it's supposed to run continuously, is it? I think all of mine have run for a while and cut out and then kicked back on again. ???

the AC will cycle on and off depending on the temp.

He's right about that...

But if you are sure the wiring is bad, make a trip to Autozone or an auto parts store that carries Standard Motor Parts. Either one will be able to get some crimp on connectors that you can use with new wire to replace the damaged wiring. All of the connectors in the socket will come out using a safety pin or jeweler's screwdriver to lift the plastic retaining clips. Then you can slip the new wire/crimp on connector in the relay socket, and cut off the old wire & splice in the new wire. Check out Radio Shack and see if they have new relay sockets. You might be better off replacing the relay & socket if you can't find the crimp on connectors.
