Preparing for Ford Nationals - Headlight Relay & Firewall Grommets

Before the trip to Tulsa, I decided to install a headlight relay harness.  There are two main reasons:
  1. Using a relay harness rather than routing headlight power through the switch allows for higher voltage at the light which equates to a brighter headlight.
  2. Since the headlight power and draw is not pulled through the headlight switch, it is less prone to overheat.  When the headlight switch overheats, the lights turn off until it cools down.
While I could build my own headlight harness, I decided to use a RedLine LumTronix (part# EH-001) from CJ Pony parts.  The harness is well made, with proper length wiring, and insulation covering the wires.  If I could improve it in any way, it would be to make the H4 connectors for the headlights just slightly smaller.  They were slightly larger than stock and would not route through the holes through the grill brackets like the factory light wiring.  

The harness was rather easy to install but there is not much to show of it in pictures.  The relays are mounted to a bracket behind the passenger side headlight.  I'm honestly not able to tell an incredible amount of different in the brightness but they do appear a little brighter.




After the install was done, I thought the dimmer switch would not work.  Upon taking everything apart, I found the kick panel was putting pressure on the grommet in the carpet around the dimmer switch.  This pressure would not let the dimmer switch work.  After a little rearrangement, it seems to be working just fine.  


As part of finishing this project and the amplifer installation, I was able to seal up the remaining holes in the firewall.  So that takes another item off the list for Tulsa.

Remaining Items for Tulsa:

Lubricate U-Joints & Check Nut Torque
Check Air/Fuel Ratio
Fix Rattle by Clutch Pedal
Fix Squeaky Leaf Sprints
Add Air Conditioning (Includes Parts to Block Cowl Vents)
Fix Anti-Freeze Leaks
Add Fan Shroud
