What is handy for this is a test light. There should be a plugin underneath the vehicle in the back. I would start there to see if there is power at the plugins back there.

Actually that was done also replaced the brake switch under the dash. It will work sometimes just for a sec as of its a short somewhere but. With the test light everything seems to get fire.

If you have constant power at that point then it has to be in the connector, broken wire. Look and test for a intermittent, broken wire on all the plugins. Wires break inside the insulation and usually at the connections.

Ok will try that. Thanks

I just had to fix this in my moms 99 Chevy silverado, spliced the left and right wires together, they were brown on left, brown and white on right
