headlight relays

I made this headlight modification on the ‘67 Dart this spring using new sockets,and 12 gage wire from relays to headlights including their grounds powered from alternator power lug using Dan’s parts. It made a huge difference, not only in brighter lights, but significantly reducing power load passing through bulkhead connector, amp gage, and headlight switch. Using thicker gage wire lessens voltage drop, and heat build-up found with the factory 16 gage conductors caused.

I did not stop with lighting, relays are also powering electric choke, o2 sensor, and soon charging circuit employing remote voltage reading. The only high draw device left utilizing bulkhead connector is convertible top hydraulic pump which also uses two relays to take the load off of dash one year only switch.

I had a few questions early on concerning design, and /6Dan graciously guided me through with clear instructions. This is a great low budget improvement, but don’t use cheap relays not rated for higher under hood temperatures and harsh conditions. Spend a few more bucks for quality parts, and do it once right.

Currently I am rerouting conductors & relays for cleaner under hood look. Also I have installed a ‘sub panel’ if you will, to distribute fused power to all the relays in under hood area which also consolidates grounding conductors & feeds for a nice clean look
