Default 92 Prelude Si Electrical Problems Please Help!!!

Hello my name is Eddie new to the site. I have owned 4 Hondas in my time including a 93 Prelude VTEC. Found this 92 SI (2.3 auto now has H22 VTEC and 5 speed) for a 'project daily driver' that's had some work done to it. Not sure if it was done right!?!? It runs and drives but has seaveral things that make me scratch my head.





Other than brakes, tires, shocks, O2 sensor, VSS, motor mounts, body work and paint!!

Here are my problems!

Gas/temp guage did not work when I bought the car. I changed it twice and both times it started smoking about 2 minutes after starting it up!?!?

The AC condenser fan stays on all the time (key is in auxilary and in on position) and I am not sure if this is normal.

When I turn the lights on the radiator/coolant turns on!

I cannot check engine codes. The wire/paper clip jump does nothing. CEL stays on constant.

Thought I should look at the ECU. Whoever put the ECU in did not bother bolting it back where it was. At some point water got into the car and sat for awhile.. This is what I found. Along with an ant nest!!! I changed to another used ECU and still has the same problems!




Wires to ECU look shady as well


These are plunges that are empty. I do not see where they would go of if they are to be used at all!!!

This one is by the condenser fan plug

This one under the distributer



Any help would be appreciated..



Thanks

Eddie

The thermostat sensor connects to the Vtec and three wires go to the ECU. Red, blue and green.

Could an after market car alarm (AudioVox APS996A) cause electrical problems? While working on the car I noticed the door locks making noise. A wire by my elbow was grounding out and cuasing the doors to lock. I looked under the dash and there it was wires all bundled up. I found out that this model controls a lot. Is removing one of these difficult?

Also I noticed when rolling the windows up they get to the top and the coolant fan starts up and stops when I release the button!?!?!? What the hell?

Could this alarm be the problem?

Thanks

Eddie
