[QUOTE="2fiddy, post: 8317542, member: 663121"] Here's my understanding of how all this works so far : 1. The transmitters connected to the head unit need power, so connect red to red and black to ground. I'm thinking 1 transmitter should work for both cameras, so when in reverse, reverse camera sends signal, transmitter picks up, sends to head unit, when going forward, push button for fog light, front camera sends signal to transmitter, then to head unit. It's the same make and model for cameras and transmitters. 2. Since transmitter needs to be powered, can't connect red from transmitter to brown wire on head unit, for head unit to automatically switch to rear camera view. So will have to switch manually on head unit, or wire brown wire to reverse wire of car. 3. So connecting red wire from transmitter to red from car harness, joining black wire from transmitter to pink wire from head unit, thin black wire from head unit, thick black wire from unit, adding an extension wire to ground in car. 4 wires to ground. This make sense ? Why 2 black wires from head unit, 1 thin 1 thick ? [/QUOTE]
