Re: 69 engine bay wiring

69 models with tach have a separate harness on the engine side for the tach hookup. The Assembly Instruction Manual (AIM) shows where exactly the tach harness went through the firewall, to the driver side of the main fuse block bulkhead.

I belive the only difference for the 69 engine harness with gauges is that it would not have the wire for the oil pressure sender to warning light circuit.

I know there are two different light harnesses sold, but not sure of the difference. Pulled up the pics of each and it seems like all the same circuits. Wait, I looked at the better diagrams here on TC, and I see that the difference between the two is that the harness for warning lights uses one position on the bulkhead connector, while the harness for gauges uses one position above. So, if your engine side harness has a black wire going into the lower driver side corner of the connector, and the position immediately above that is open, then all you should need to do is move the wire to the open position above.

You can PM JimM for a password to get the more detailed PDF wiring drawings for 69, I think.

Re: 69 engine bay wiring

Engine side harness for a guage car has the 2 leads in it for the ammeter, and single lead for the oil pressure gauge. Thats the only difference. Tach is a separate wire, and the temperature sender uses the same lead as the idiot light. The inner underdash harness routes it to the console instead of the dash.

Re: 69 engine bay wiring

Isn't the oil pressure gauge mechanical, and therefore there would be no need for a wire to the sending unit? Or do gauge cars have both the warning light and the mechanical gauge?
