Hi Guys,
I've got a 1988 Chevy G20. I installed a CB Radio with the wires going into the overhead map lights. All was well until the wiring pulled out a month later. Got a little help from a friend and well.... Now when I shut off the van, the battery gauge does not die with the engine as it should. The orange wire for the gauges seems to be the culprit. Any thoughts or diagrams? It's a mess as there's some white wires that seem to have been added before I bought it.. But maybe If I can see some kind of original?

First having a copy of the shop and electrical manual really helps in answering most questions on how the systems work and steps for replacements and trouble shooting. First are the overhead dome and map lights stock? If yes the electrical manual will show how they are wired….If not there should be 3 wires….a ground, a 12 volt feed from the battery (for the map light…un-switched) and the feed from the door light switches for the dome light which could be either a ground feed or a 12 volt feed. Hope this helps…Good luck.


Recently purchased (10-2021) a 1991 Chevy G-20 “Shorty”. Past vans are a 1976 Chevy G-10 (purchased new in 1976 & sold in 1995). A 1978 Chevy G-20 Shorty purchased in 2010 and sold in 2015.
