Here are pics of the install of the TM 77 Signal Booster
Sorry, even though I rotated all of the pics and saved them they still uploaded 90 degrees counter clock wise.
First connection was ground. The small silver dot in the middle is the ground point that I connected to
Next came connecting to the generator's 12VDC input lug
Then installing the switch with 3 leads (12 VDC in, 12 VDC out, and ground)
Then installing the booster.
Doing it in this manner allowed me to install it without having to run power from a compartment light.
Double click the pic and then click to enlarge and they will display in the correct orientation.
