Does anyone have the part number for a 1989 5.0 ac wot cutoff relay and for the connector harness? My harness had and connector basically disintegrated on me so I want to splice in a new one and put a new relay on as well since that looked a little rough at the connection. I can’t seem to find the correct relay online and the ones I do find don’t seem to match up with the pin connections. I attached a photo of the relay pins.
Thanks,
Brian

This harness can work. You need to cut off the small alignment rib.

It’s a standard 5-wire relay socket, and one of the wires is not used.

I used this to repair my WOT relay harness not too long ago

Thanks a ton, I was looking at that connector but wasn’t sure if it would work. That helps a lot.
What relay did you end up using or did you only replace the connector pigtail?

I used my original relay, so unfortunately I don’t have any info on a replacement

The fuel pump relay and AC cut off relay are listed as the same part number on rockauto, can get the connector too. I have used the relays interchangeably. It is nice to know that if your fuel pump relay craps out you can use your AC cut off relay to get home.

I looked on rockauto and they had 3 relays available. A standard motor products relay #ry46, a wve 1r1294 & a relay #ry46t listed. It looks like the ry46t has 5 terminal post connections. I couldn’t tell on the ry46 or wve from the photos. My current factory relay only has 4 terminal connections. Which one did you go with?

The WOT only has 4 terminals, but it's a standard 5-pin relay just missing the 5th pin, so that extra pin won't be used.

This one looks like it might also work. I don't know if it will but At least with Amazon, if it doesn't work you can return it.
