Front light harness routing

[Gentleman Jimmy]

Can someone remind me/ show me how the front light harness is routed across the core support?

I can’t remember if it goes out the drivers side lower hole and under the core support or what? I don’t have my condenser or radiator in right now and don’t want to route it the wrong way and have to re do it when I go to install those.
Thanks

Iirc it goes down driver fender and runs across between rad and core support. Should be a couple of @1/4" holes for the plastic clamps to push into.

It goes out below the drivers side light , pinned 4 places to front bottom of core support and back trough the core support on passengers side.

I don't know what year Blazer you have, but if you have the push/pull headlight switch in the dash, right now is a great time to get a new light harness with a switched relay at the battery vs. running the antique wiring from the battery to the dash switch and back. I noticed a big difference when I switched to a harness. My two cents.

You are correct, relays make a big difference in older vehicles! Mines an 89. I have rewired everything from the bulkhead to the rear of the vehicle already and for the first time I have reverse lights, license plate lights, and a proper trailer harness. The PO had so many terrible splices and cheap wire, it was easier to just replace it all.

I removed all the loom on the front harness and repaired anything suspect, mostly the grounds. I will be adding relays for the headlights and window motors too.

Got the harness all finished up, wired up relays on the lights. All is good now looking forward to some better lighting.
