I have a '72 Blazer and I put a new turn signal switch in. When I disconnected the half moon plug under the dash I noticed that one of the dark blue wires is fried. The wire attaches to the switch on top, so it would make sense that it's hot when the lever is up (right turn) and there are 2 wires going out of the half moon plug, is it safe to assume that it's probably the right turn signal? Does anyone happen to know what wire that is? I tried following it through the firewall but I loose it the harness. Hoping to narrow it down before I fire it up and fry it again (the switch was broke and the wire was fried when I bought it). Thanks, Mike.
