Need help with simplifying the harness for my EV

[ehansen007]

Hey guys,

After staring at the wiring diagrams for a few days I'm still having problems trying to identify how I would use the lighting switch in the car and map it over to my basic hot rod harness I bought for the car. I basically have two flasher relays for hazard and turn and not sure If I even need to run a hazard setup. Can someone help with a simplified setup and/or help me understand what the abbreviations are for in the Lighting switch and dimmer switch? What is HF, HU, HL, E?. How about HC, TC, and EL? Nowhere in this wiring manual does it give the translation. Thanks.

HU = Headlight Upper(High beams)
E = earth or ground
HL= headlight low beam
HF = head lights flash momentary Turns off lights
HC= ?????

The head lights work different.
There is always 12 volts to the bulb. You turn them on at the switch by taking the wire to ground.
If you want to use a standard system. you should start over on this wiring.

Found it on Nasioc (of course)

Quote. I'm currently considering trying to put the DRL function over to the fog lites, from the low beams...over in this thread

Some of the switch terminal designators have me stumped...

On Dimmer & Passing Switch, there are four terminals--
HF--Headlamp Flash, I'm guessing...energizes the hi beam relay
HU--Upper, or high beams...completes ground path for hi beams
HL--Low beams? doesn't show any connection on diagram, however.
E---Earth, for ground

On the Lighting Switch, three terminals showing--
HC--energizes the DRL relay (completes path to ground)
TC--?? shows no connection to anything on diagram..
EL--connection to ground

Any idea on the "HL" and "TC" terminals? I don't like assuming they are "unused"...automotive "pictorial" schematics always make me wonder what might have
been left out...


TC appears to be parking lights.
HC may stand for headlight circuit

HC= headlight control. This turns on the 12v positive to the headlight bulbs.

TC off the light switch feeds FB-11 Relay.
That feeds: Everything that lights up in the car when you turn on the lights.
