Arny Posted February 22 Share Posted February 22 Sorry for that stupid question - but can someone tell me where the INBOARD dash junction block is located? The truck is a '88 RW713. I'm trying to track down some electrical issues but so far I was not quite sure where that juction block is located. Thank you guys!

Joey Mack Posted February 22 Share Posted February 22 I dont recall a junction block, but theres 2 buss bars on the firewall near the steering shaft. 14 or 15 posts each. What has failed ?

What has failed ? I was trying to reinstall the back-up light. According to the wiring diagramm the wire changes the color from that mysterious inboard junction block on. That junction block is supposed to be between the fuse box and the back-up light switch. I also just found the buss bars on the firewall outside the cab.
