LS firewall harness routing - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm doing a clean up on my 61 firewall and am looking for a stock cleaned up look not a custom look. I have already filled in multiple holes and drilled a new hole for the chassis wiring harness and am wanting to put the hole in for the engine harness. I have a stock truck 5.3 with a BP swap harness. The cab isn't on the frame and the frame is at another location. I am wanting to put the computer under the seat. Anyone have any pictures on where they ran the harness through the firewall?
