I put in all new wiring in my 80 for the trailer lights. A few weeks ago when I plugged in a borrowed trailer, the original Toyota diode pack died - so even with the trailer disconnected I kept blowing fuses. Probably a fault in my socket, the trailer worked fine on another truck. So I picked up a Tekonsha tow wiring package with the isolator. I still had leftover Sumitomo crimps (the vast majority of my 80's connectors use these) from the locker install, so I modified the Toyota Y harness to add reverse lights without using the T taps - the blue double crimped wire in the pic replaces the original red wire. The potted isolator lives on top of the spare tire cross member, as well as the coiled up mass of too long cable back to the socket. If I get really bored I'll shorten that cable.
To do: bring the trailer power wire across the radiator support to the second battery. I don't have a trailer that uses that pin, so no rush.
