I've have used both, a $450.00 Painless 18 circuit kit and the $179.00 Rebel 9+3 circuit kit. These kits are best suited for modified trucks, not so much if your restoring an original truck.
The Painless kit had everything I needed to wire my truck including headlight pigtails, fuses and more. I chose that kit because I was building a '52 Chevy truck street rod from the ground up and needed everything to complete it. This kit was perfect because I have a late model GM column with ignition switch on column, electric wipers with delay, power windows and heater. I may add A/C later. Great harness kit, with a nice instruction manual.
When I rewired my buddy's '56 Chevy pickup, also a street rod, I used the Rebel kit. His truck already had new headlight pigtails from NAPA and is really a pretty basic truck. The Rebel kit is a good quality kit for the money, easy to install and Made in the U.S.A. You'll need to purchase some items like fuses and tie bands to complete the installation. But hey, that's how they keep the price low. A nice harness kit, instruction manual not so good.
Bottom line, you get what you pay for.
