Anyone know where these wires go to

[Creomod]

Hey there guys I have this car it’s A 89 just wondering if you know where these wires go to. I can see the black white wire with the circuit breaker for door locks or power windows but not sure what the other 2 ends are for. Also see a yellow black stripe wire that’s cut (defrost) & red/yellow wire. I also see a black wire in there next to these wires that a ground can I hook it up battery terminal?

Also I noticed the blue/red wire that should go to starter soloniod they ran a wire straight to ignition switch why would that be done?

You need wiring diagrams. Someone here will have them for an 89. You are gonna have some wire chasing to do to find the issues as they just bypassed stuff and didn’t fix.

You might want to hit @Mustang5L5 up and see if he has them. Pretty sure his whip is an '89.

This wire here is the washer fluid pump test plug. Just tape it and tuck it

As for the other wires, will need to search the wiring diagrams.

Link here to 1988 but that harness on that side of the engine bay would be identical to 1989

1988 Mustang EVTM

1988 Mustang EVTM SImilar to 1987 and 1989 with minor differences in engine harness. Most non-engine related stuff is identical, such as power windows, HVAC, defrost, etc.

Thanks brother I thought it was the wire for the hood light. So it’s the test wire for the washer pump. Can any of these wires go to the windshield washer resivor connector?Also I found this pic of wiring near Solonoid and I see a connector at the top of pic and it appears to have the red/yellow wire and the yellow/blk wire maybe that’s where these 2 wires go. Can you look at the pic maybe you might know what connector that is? You can barley see it at the top of pic but I think pic is upside down

What colors/stripes are those 4 wires?

You have a Red/yellow and yellow/black wire for the low washer fluid switch to the bottle

 

[Mustang5L5]

Yes, this plug in this pic is the low washer fluid level plug

Here's a detail on where it connects

The other plug connector you show is the pump motor plug

Thanks a lot I tore into another car to look at wiring now I have a new issue a wobbling harmonic balancer and a cheak engine light haven’t hooked up the reader I’m assuming it’s the balancer the rubber seal is barely moved a little popping out one side hope it’s that

A balancer issue will not turn the CEL on.
Change that balancer, it's pretty rude when it comes off with the engine running.
