Step three - Wiring

Next Step was Wiring RoadToad so that the Brake, Turnsignal and Running lights of RoadAbode would send the signal to RoadToads Rear Lamps. Since you are suppose to NEVER backup when the Toad is attached, reverse lights are unnecessary.

First Step was running the Wiring from the kit we purchased from the Front to the rear of RoadToad. The cable is flat and consists of 4 color wires; green, yellow, brown, and white. I started at the front while the front fascia was off - there is a mounting for the cable end built into the baseplate - and using cable ties ran the cable along the bottom edge of the radiator mounts, Up and under the Air filter box, and to the passenger side firewall. Now came the fun part - getting thru the firewall. With Kimberly as my helper, we used coathangers to fish thru an existing wiring hole in the firewall. It even has a protective rubber boot! There by the passenger side door is a panel to access the fuses and wiring. We used a second coathanger to grab the first - and we were thru!
First Step of wiring - got it into the cockpit. Now to get it to the back of RoadToad.

We lifted the kick panel along where the bottom of the door sill meets the door on the passenger side. This was pretty easy, only held down by two or three clips. Did the same with the cover for the seatbelt retractor and the backdoor sill. Underneath these was a channel to run alongside the existing wiring. We used the coathangers again to feed thru to the trunk, behind the bolster padding next to the backseat, following the existing wiring's path. The light wiring is now in the trunk! We next popped the fasteners - same ones used on the front of RoadToad - and peeled up the carpet/matting.
Behind the carpeting were the connectors for the rear light. Trying to decipher which wire served what purpose. When online, trying to find a Honda wiring diagram - no go. Tried my House wiring tester - voltage is too low to get a reading. Trip to Pep-Boys! Got the tool I needed, a $3.49 circuit tester.
As Kimberly and Emily (they took turns!) hit the brake pedal and flicked on the headlights - I tested and found out which wire was which. (see Bad Pic on the right) Since RoadAbode has combined brake/turnsignal, I do not have to separate the wire for the turnsignal - We'll just use the one bulb in RoadToad.
Next part was the part I disliked the most - cutting the existing brake and running light wires, installing the diodes to prevent the two systems from connecting to each other, and wiring in the new. First connection had to redo, connected to the wrong side of the diode! Once I got over the hebee-jebees of doing that, the other 5 connections (three per diode) were a snap! Made sure everything was tight, taped up, and tested - and closed it all up again. Finito! Next, wiring the front end wires to the 4-prong plug.
