Headlight Relay Yes No

My opinion... Issues with bulkhead connectors and ALT' gauges are blown waaaay out of proportion by the internet. I suspect for every 1 failure reported there are dozens more out there with no fault. Some will link bulkhead connector and those Madelectrical webpages to every electrical fault. Truth is the actual fault probably is/was somewhere else. Only the evidence or results appear at that connector. Bypass the connector equals moving the future fault evidence somewhere else, and likely to a place where it isn't so easily found. So... Headlight circuit changes or no, If/when there is a fault and or overload occurs at wiper motor, blower motor, whatever, where will you find the melting/burning ? Outside the firewall or all about under/behind the dash ?
I stated before. Headlight relays or any relays are used to lessen the loads on manually operated switches. In our cars, increased load could only come from different that OEM type bulbs. If OEM type bulbs are used the headlight switch will only be replaced due to the historically typical failure of the included dimmer rheostat.
Again just my opinion.. Those who suggest "bypass this and that" should first take long look at how and why it was built a certain way in the first place. They just might find there was a 'method to the madness' and they aren't really smarter than those OEM engineers after all.
