wire harness
 

I'm going to look at a engine harness for my truck but the guy can't remember if it's from a warning light truck or a guage cluster truck. is there and easy way to tell the diffrence just by lookign at it?

Also he thinks it's from an 80 and mines an 84 will they go together?

The price is right so i just want to make sure.

All the harness diagrams I have found and were given to me show 73-87, I would think they were the same and the gauge and light wont make a difference in the harness itself, only the cluster and the sensors
