EZ Wiring Harness - Lightin' The Fire

This compact brake light switch was sourced at the auto parts store, though I needed to add a small bracket to the pedal assembly to mount it. Turns out it kept blowing fuses, as when it activated it grounded through the metal parts, meaning I had to insulate it after this picture was taken.

EZ supply these ready-wired connectors for a GM column-mounted ignition switch but as I was using an aftermarket dash-located ignition, I had to remove the connector blocks.

We won't show all the EZ Wiring instructions, but they're pretty clear in the main, as this ignition switch diagram shows.

A good ground is imperative. I elected to drill and tap the steel under-dash framework and use a bolt to secure a number of grounds in one location, after I'd removed the paint of course.

If you're including a removable dash panel, or in this case an indicator switch panel, it's a good idea to make the wiring removable for future servicing. Better to work on the bench than on your back under the dash huh?

The flasher units come pre-wired in the EZ kit, but with no mounts. I fabricated this little panel from aluminum angle and mounted it to the brake pedal bracket. The flashers simply sit in the holes and are easily accessible.

The only head-scratching moment with the installation came when it came time to wire the aftermarket turn signal switch. With a number of such switches on the market, the EZ instructions can't be expected to show diagrams for them all, but call `em and tell 'em what you have and they should be able to help you hook it up.

Here's the complete kit, supplied by EZ Wiring, complete with the fuse box with wiring already attached, as well as flasher relays and plastic connectors to hook up to an ignition switch. Also included are headlight connectors, the necessary connectors to connect to a GM column and alternator, GM turn signal connectors, a pre-wired dimmer switch plug, a fusible link for the starter motor, cable ties, rubber grommet and instructions.
