kaua'i datto Posted June 25, 2011 Report Share Posted June 25, 2011 I was wondering if there is someone who could tell me where I can find a wiring diagram I recently purchased a 73 620 from my cousin who fried some wires connected to the alternator running into the cab and I have no idea what the problem is and what the wire's are for Quote Link to comment

kaua'i datto Posted June 25, 2011 Author Report Share Posted June 25, 2011 Ahh I see its a group of wires leading from the pass side of the engine bay through the firewall behind the glove box connected to a 4 or 5 pin connection Quote Link to comment
datzenmike Posted June 25, 2011 Report Share Posted June 25, 2011 If you have a '73 can I assume you have swapped a NAPS Z motor into it? Are you using the NAPS alternator or the '73? If using the NAPS you will have problems. Otherwise everything should wire up and run just fine. Quote Link to comment
