I left the zipties loose like big hoops and ran wires once at a time for each component. Once i was sure i was done i tightened all the zipties and pulled the harness to tape it.
For my blazer i removed the factory fusebox and wired in 2 seperate boxes higher in the dash. I made most of the changes just from the firewall to the boxes. It was a lot of wire extension but i also wired all of the power feeds from the battery to the boxes in a bus form instead of individual power wires like it came with.

i just get really nervous dealing with canbus and all that stuff. i had heard that if some wires get too long or what have ya that things won’t read correctly or things won’t work properly. how true that is i’m not sure, but still

Reason: incorrect spelling of “canbus”
