Cool Tech Wrangler tow harness

well, thats the beauty of the Mopar setup... it literally splits the main harness and uses isolation relays to switch between the 2 voltage source. If Mopar is designing their RV harness this way, they must have a reason to do so... (note: backfeeding)

Yes, except I was using relays back in the 1950s. Relays are dead now. They use SCRs, diodes, resistors, capacitors, and transistors in micro circuits. I just think people are trying to make this MH to toad hookup way too complicated.

This is quote is taken from another thread here called "Cooltech Wiring Harness for Jeep TOAD" and was said to be a responce from Cooltech.

Quote:
"ALL previous model Jeeps prior to the introduction of the JK Wrangler from 2007-current would require diodes. The JK utilizes a CAN-BUS electrical system. When you "flip a switch" in the JK, more often than not, you are not completing a circuit (through a relay). In fact, when you flip a switch, you are sending a request signal into the car's CAN BUS system. The Power Distribution Module is invoked with the task of making the connection. This combination of CAN-BUS and the power distribution box eliminate traditional feedback - as long as the system is wired properly. We have several hundred tow harnesses on the road and I would venture to say we have the most popular Wrangler harness on the market. We wouldn't have this success if the system didn't work. Note that we also sell a solution for older model jeeps - 1996-2006 Wrangler TJ's. Rather than use diodes and "hack up" your OEM wiring, our solution uses separate bulb and sockets. This too is a popular solution - because it works.

Ummm, I dont think so. Relays are very much alive... none of those you speak of can replace the simple electro-mechanical device. Just look at how many relays are in any automobile, MH, jets etc.... they are even making electro-mechanical relays on a nano level... But yeah, I agree... they are making the toad hookup way complicated... the industry standards are in sad state.

I do suspect you will have more failures in mechanical relays than in diodes. That is why auto manufactures plug in relays & solder in diodes.
