Swapped in the b17, had a lsvtec everything was fine.
Now, the fan has constant power, only works if you ground off one side at the connector. If I jump the switch on the thermo stat nothing happens.
My running lights instantly pop a fuse when turned on. Took out front bulbs but guess its in my wiring.
Where should I start with either issue? Relay? main ground?
Thanks in advance guys!

 

The 92 Integra rad fan power is constant, fuse 12-15A, [hot at all times] in under dash fuse box, the rad fan relay supplies the rad fan with a ground, the relay is controled by the ECT switch that supplies the rad fan relay with a ground, [yellow/green lead].

That is where I would start, [rad fan relay] make sure wiring is correct..
Black- ground
Blue- ground output to rad fan
Yellow/green- ground input from ECT switch, [when engine coolent is 192 degrees F]
Black/yellow- 12V input, fuse 21-15A, [hot at all times] in under dash fuse box.

Make sure you are not confusing ECT switch, [yellow/green and black leads] with the ECT sending unit, [ yellow/green and grounded through sensor].

Sorry I am not sure where the switch and sending unit are on a B17.


For the lights it must be a wiring issue, if you have an aftermarket HU in the dash, pull it and check the red/black lead, [illumination] in stock radio harness, make sure it is not shorting to ground. 94

 

Awesome info thanks, Is the main relay for the fan on the passenger side radiator support?

 

Yes, I believe it is right in front of batt. on G2s. 94

 

Thanks bud, working on it tomorrow on my day off, I'll keep posted on both issues

 

Your awesome! Pulled the stereo out and that wire was exposed, taped it up and no more blown fuse, thanks alot! Is that just for the illumination on the stock stereo?
Working on fan now
