That's a simple one. Look at the wires that you do not want, and follow them, see where they go to. If they do not lead to this non A/C resistor that you're speaking of, or something else that you do not want, cut! LOL.

I think you hit the nail on the head with your original question.

I personally would never cut a wire without seeing where it goes. Well, I did once. I knew it was speaker wire, just didn't know which speaker it went to!

 

And that's what I started to do today, until I realized a purple wire came from the fire wall, went to the resistor, then to the relay, then to another plug. I mean WTF!! How am I suspossed to cut a wire like that, when it goes to the only two things I need.

 

If it's really as confusing as it sounds, I'd honestly just leave the wire there. Is there any way you could show us a picture of this pesky wire?

I mean if worse comes to worse, yet you really want a clean look, just buy a few of them little plastic wire clips. Run it in a straight line, or tuck it out of the way the best you can, since you don't want all of your wires hanging around, no pun intended. LOL.

 

Ive been debating that. But heres the next issue, on the non ac box theres his little connection to the bottom left of the blower motor. Its not the ground and comes with its own little plug. How would i wire all that into the mix? I hate electrical, period.

 

Without seeing it, I'd have no clue. I'm right there with you, I hate messing with wires. Just clipping all of my radio wires, heat and A/C wires was a huge pain. I finally had to lay down a blanket, since I was sick of getting scratched by laying on the bare metal floor pans while cutting and capping.

Messing with wires in the engine bay isn't as bad though. Especially since I have my hood unbolted, I don't need any outrageously bright light beaming under the hood, I can use the lights on the ceiling of my garage.

 

If I were to take a picture now you think you could help me out a little?

 

Possibly, but I'd still have absolutely no clue which wire was which.

I've heard the whole "paying someone to work on your car is like paying someone to (blank) your wife", but when I buy some Autometer gauges, I'm heading to an audio/electrical shop and just paying to have them installed. Around 200 dollars I'm guessing won't be all that bad. That's about how much shops around here charge to install subs, amps, and to wire up a new head unit at least. I'm assuming gauges won't be much worse.

I just hate messing with wires that much.

 

Well at this point in time.....**** my wife, lol. If I even had one tho Im seriously debating about going to the dealership and being like "i want this connector, that one, that one, that one, and that one gone." But i know they'll charge me an arm and a leg to do it. Hey Twin, looking at your photos I know your amazingly good with cars so if you could help me out, that would be GREAT. K thanks bye!!

 

Yeah, Twin would be way more help than I. He's got some amazing cars, including that Vette of his.

 

What wires? If you swap over the relay and the resistor you should be able to use all wires you had. There's simply the resistor bridge, the hi speed relay and the blower motor, that's all. The "other" wires must be from something else like the hood light and the AC pressure switches. Those can be simply taped away (my original non AC 88 has all those connectors, they are simply tied away w/ zip ties)

The little L shaped terminal that bolts under one of the blower motor bolts is the blower motor ground. Your wiring harness should have a single plug that fits it.

You can see it here:


The purple wire is power for the motor. If the blower is switched on 12V goes to the resistor and depending on the selector setting one of the resistors is active. There are 2 purple wires in the resistor connector, the 2nd goes to the hi speed relay and when switched on it bypasses the resistor and full 12V is switched to the motor via the relay.

Here's a close up of some wiring, maybe it helps.

 

Okay and how do I wire in the blower motor? What colors go to what.

 

purple to motor, the l shaped tab is a ground. That's all. The purple gets voltage from either the resistor or hi speed relay depending on fan speed setting on your control panel

 

I know that there's a purple to the resistor and to the relay. Then my blower motor has the connector with orange as the wire color. Ima take a picture and show you what I'm talking about if you don't understand.

 

The orange was the color coding on a non AC car. Did you remove the original wire that came w/ the box & blower motor? You have to remove that cable, it plugs into the non AC resistor bridge. You will not be using it, remove it as you did the resistor bridge. All you need is the housing and the blower motor, nothing else.

Here's my 88, original non AC car, orange wire is power to blower motor from resistor bridge. AC car has that replaced by pink wire because of hi speed relay

 

Mine looks exactly like that. I have the resistor and the relay swapped over to the new one the ground I have figured out that's not an issue. The previous owner cut the wire where you'd see it past the relay. The taped up part. I just done know how to wire the blower motor in still, only because the thing that plugs into the blower motor is still connected to the non ac resistor.

 

So this is what I did. The non ac box came with the blower motor plugged into the relay and
The ground. I took out the resistor and switched it with the ac resistor. I hung the relay off the box like you did and I plugged in the ground. I'm still getting no power to the motor. How would I splice in that connector that's on the bottom left of the blower?

 

Ohh i get it now what your saying TWIN....my bad. What ill need to know is what purple wire off of the relay has to go to the motor. That wont be an issue for me to get it wired up.

 

I'm kind of glad to see you got a little bit of help with this issue after all. Sorry I couldn't be of more help, wiring just isn't my area. LOL.

 

I know right im soo much happier now.

 

Trace the purple wires. One goes to the resistor, the other should go to the blower motor. The resistor has 2 purples paired in one terminal (the one on the pass side that's stand alone).

It's the purple one w/ the ribber plug on the motor.

 

Hey TWIN, so that purple wire and the connection that you have, i dont have. Im not even jokin its like non existent. How can i make this work with what i have from the non ac car and my current wiring.

 

Ahhh nvm i got it. The connection with the purple wire it, gets wired to the blower connections for the motor control. Only thing is now, i don't have high speed.

 

The relay bypasses the resistor and puts full 12V to the blower motor. Either the relay is not tripping or it's not wired in.

 

i hear ya! I want to know too! there is mainly a big black connector on the passenger side bay! i hate it!
