First off dont trust a test light. Most are setup to read from 3v to 12 volts. You could have a partialy blown fuse or corroded terminal that will allow 3 volts across it and nothing more. Most circuits in the car from the fuses needs 12 volts to function. Get a multi meter and test with that...

If you have a good aftermarket stereo it should have sub control on it. No need to run a bass knob. To get a 4ohm speaker to 2ohm you would have to parallel the speakers. In order to do that you need two speakers or dual voice coils. If you are doing this with say the fronts, you connect both...

Are there any lights on the amp at all? Could be that you blew a speaker and it is putting the amp into protection. Like was said above get a multimeter and test the connections on the amp to make sure you are getting power and ground to the amp. If you are and your amp is getiing power(lights...

Ign wire should be black/white, 12v constant should be white. Heavy gauge wires coming from steering column.

Glad to hear it.:thumb:

Not sure what they should read as far as resistance but they should click on when engaged so you should feel or hear it. You might do a search on here for mpi just make sure you highlight Titles only under all posts.

I just did mine on a 91 laser. The plug behind the pass headlight had four wire. Blue small guage black small guage these wire went to the temp sensor for the bottom radiator. Then Larger gauge blue w/red and blue/black went to the fan. Blue/red was 12v blue/black ground. I installed relay...

Should be an armed output on alarm. If it made by Dei it should be an orange wire off the main 7-9 pin harness. You would wire that output to 85 of the relay. It is a neg trigger. You wire 86 to 12 volts. You do not use 87. 30 will go to the fuel pumpside of the wire and 87a to the other side...

Did you rewire your fuel pump? Could have a bad relay or a wire could be shorting back there.

Easiest thing to do is disconnect power 12v Ign and ground from the radio. Run your own 12v and Ign to the ignition switch under the steering column. Ground your own source to the chassey. Cap off the wires not being used behind the radio. What it sounds like to me is that you have an...

MPI relay/fuse, Bad ECU?

I know that it is wired to run off my temp. My question was only if I needed to hook up the other sensor from the ac fan. I ment to wire it that way. My car overheated and made me question the other sensor. I believe I had overloaded the factory circuit. I am going to wire a dual relay as...

That is exactly how I have mine wired. I was at my friends house when I did the install so was not able to wire the relays in. I will do that when I get a chance. Thanks for all the replies. On my factory wires I had blue as positive and black as negative and on my spals it was the same colors FYI

Agreed. I will put a dual relay inline on the passenger side to make sure that it is getting enough current without overloading the factory circuit. That was my only question (box on ac fan) I do know how to wire relays up as I work in Car Audio Installation. We usualy have a ton of doorlock...

That is the way I have them wired well not in series but in parallel. In series I would think it would cuase one of the fans to push instead of pull since they are not dedicated pollarity. I am at work at the moment and my car is at home. I have not had a chance to go over the wiring. Since...
