So I reinspected the engine bay wiring again, and found nothing that appeared to be damaged. I pulled the instrument cluster....and lets just say its a real mess back there, there are at least 2 wires that 'appear' as though they should have been connected to something at some point in time, but no longer are. This is only complicated by the butchering of the wiring done over the years back there by the addition of things like gauges (previous owners) and the stereo, fan and MSD which was done about 10-15 years ago by a family friend.
The only wiring I have done recently is add LED tail lamps with electronic flasher, and a new turn signal switch.
Now here is the current list of things electrically speaking that I have determined are screwed up as of now.
1. Oil light- stays on with ignition off, turn the car on, it gets oil pressure, light goes off, turn the car off it stays off. Turn the ignition back on and it will then stay lit if you pull the key.
2. Dash lights & blower are not working....seem unrelated
3. Horn stopped working
4.Turn signals not blinking correctly- but I have concluded its a bad socket on the passenger side front. I don't believe this should be related to any of the other problems.
The wiring for the turn signal switch was a pretty straightforward replacement, and was buried in the dash so I didn't have to mess with anything else, but I suppose I will go and double check the connection.
I need to get a wiring diagram to help decipher what is what under the dash. anyone have an electronic copy of the diagram?
I am half way to the point that I just want to pull it all out and start fresh and get a new harness designed to handle modern components. But the thought of wiring that much pretty much sickens me.
