For your '50 Ford, if you buy from one of the reputable vendors, there is a main harness and MANY smaller harnesses.

For the main harness, about half goes under the hood and the other half goes under the dash. I always start by removing the old harness, noting the exact point where it passes through the firewall. Also note all of the wiring clips - you will need them for your new harness. Your camera is your friend. Under the dash, pay attention to where the old harness passes over the speedometer.

Your new harness should be clearly marked and color-coded, so you need to get the old one out of the way. Run your new harness from the inside to the outside, stopping at the correct point between the two sides.

The easiest part is connecting everything under the hood. Oil sender not a lot of fun, but the rest pretty straightforward. Under the dash will frazzle your nerves and strain your neck. Just take your time and it will go quicker than you think. Some people like to remove the front seat and use a pillow to support your head. Not bragging, but I once installed an entire main harness in my '50 Crestliner in one morning.

After the main harness is in place, now you can work on other harnesses. Parking light harnesses (2), headlight crossover harness, headlight and parking light bucket harnesses, etc., etc.

Good luck.
