1st gen electrical plug behind ABS

I was wondering if anyone may know what this plug may be. It was tucked behind my ABS unit on my first gen taco

 

Just what year ?engine trans 4x4 ??

Do you have any electrical devices not working ?

Just what colors are the wires hard to tell from the dirt

 

Could be for the windshield washer pump or sensor on non-cold weather equipped trucks.

 

@Wyoming09
It's a '98, 4wd, manual trans. I've had the truck for just under a year and everything has seemed functional. I'll try to clean it up some and get a better look at the wire colors. I have difficulty determining wire colors, so may just have to post another picture

@BartMaster1234
What's the purpose of that on cold-weather vehicles? (I'm in central CA, and I think the history of the truck has been fairly local. I should have a vehicle history report somewhere...)

 

Auto antenna motor. Connector A8

Wiring diagram below.

 

All PreRunners and 4x4 are cool weather equipped, just means you get the 2.0kW starter instead of the lower powered one, and your washer reservoir is hidden in the wheel well versus a standard tank under the washer motor.

 

@HAVOC Thanks for the explanation and diagram!

@BartMaster1234 Interesting, good to know

 

Does anyone know if the master cylinder ports are split 50/50?

I'm in the middle of an ABS/LSPV delete and looking through some threads. Seems like most are running the rear off the rear port, but with the former ABS setup, I conveniently have access to the front port (for the rear)

 

I'll be running a manual proportioning valve of course. Just wanted to know if the the two ports on the MC function the same internally
