my son has a 2005 evo, he brought it to me due electrical issues. I found the junction block drivers side under kicker panel to be full of corrosion and bare wires. We rewired and bypassed the junction block and car was good again till two weeks ago. Mow some vehicle systems some work and some have no electric. Briefly the dash lights, starter and turn signals do not work, is there a common power supply circuit for all these? If yes want would be the color coding.

Thanks from me and also thanks from my son who wants his evo back
