2015年11月9日 · This is Part 1 in a series of tutorials that will show you how to build a Bussmann RTMR fuse/relay block. If you’re not familiar with this product, it’s a simple waterproof enclosure that allows you to connect accessories on your vehicle through relays and/or fuses.

This allows you to use the secondary internal busbar as a ground point for pin 85 of the relays. I’ve shown you a wiring schematic that details how to connect accessories and switches to the RTMR. We’ll be using external busbars in conjunction with the Bussmann RTMR to use as grounding points for all accessories.

If you remember from earlier, the switches are wired with two different grounds. One ground is for the upper dependent LED, which terminates at the Bussmann RTMR. The second ground is for the lower independent LED. The reason we need two different grounds is because of how the dash dimming circuit works. Let me explain.

To connect the main power and ground sources between your battery and the Bussmann RTMR, 4 AWG welding wire is a good choice. Parts used in this tutorial: Wiring for switch harness: GXL 18 AWG blue, green, orange, white, yellow, brown, red/black

2016年9月5日 · The main thing for me in this project is that I wanted all the circuits to have a common ground. I didn't want to have to look for a chassis or body ground point for every accessory I installed. In a nutshell, I wanted to plug in my accessory to the RTMR pigtails & go.
