I own a 1948 GMC 1/2 ton, put a 305 w/alternator, 12 volt
System. Question: do I need reducers on all my gauges?LMC truck said Not on amp gauge, how about Oil gauge, temp gauge, fuel gauge, aren't they all mechanical?
Bought a EZ wire 21 circuit harness, I assume this harness will be fine. Just wondering about these reducers. Any help most appreciated.
