Idiot Lights to Rally Gauge, Wiring Help
 

Hello,

I am planning to switch my "idiot lights" to a rally gauge in the coming weeks. I know some of the senders need to be replaced but I'm looking for exact clarification. Also, in the past, I saw a diagram that showed the two wires in the harness that needed to be changed for rally gauges.

Is this a big pain to swap or am I just a chicken about wiring jobs? :p

Thanks all.

Its an easy swap. Just switch two wires in the connector.
Here's the diagram from my GT-37 website:

Like he said it is an easy swap. I put factory tach and gauges in my 1971 GT-37 and besides swapping a couple of wires around I had to add a tach lead. :cool:
