1966 c10 looking for LS harness routing ideas for a clean look - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I smoothed out my firewall and wanting my wiring harness to be as subtle as possible. I plan on mounting the ecm in the cab behind the glove box, was thinking of doing a DT style bulkhead connector so my body harness and powertrain harness connect and route in one spot out of sight. Anyone have any ideas or pics would be great of their setup.

I haven't done a LS swap in a c10 yet but I did do one in my 69 Camaro and I wanted the harness hid as well, I drilled the hole behind the passenger head, it may depend on the harness you have as well

bulkheads look really cool, you just need to be a bit careful with its # of connections and wire size specifics.

Who's harness are you running?

I'm not sure about the room behind the glovebox on a 66 but on my 81 it was a nightmare trying to stuff everything behind the glovebox..if I had a do-over I would have run the harness down the back of the engine on top of the tranny and done all my ecm and fuse block work either under or behind the seat..

That's prob a better location for the harness under or behind the seat, anyone have any pics.
