depends on how far you want to go.... i started just by stripping off all the loom and tape, separating groups of wiring that went the same direction, probably should've labeled some things but i didnt have any troubles with getting everything back where it goes.
i removed downstream o2 sensor wiring from both sides, pulled back and rolled up the battery amp meter (battery is on driver side) and rolled up maf sensor wiring cause its closer to ecm now also.
i routed everything to the firewall below the master cylinder instead of jumping over the header.
theres a bit of progression as i was doing it with the stock manifold then about 1/2 way thru i decided i didnt want to do this all over with the hi-ram, also had adapters on the fic injectors i had annoyed me so i swapped all the connectors on the harness to the correct ones, routed everything thru the tunnel of the hi ram.
have everything to remote mount the ignition coils too just need to find good place to put them and change that wiring..
driverside of engine - wiring for the coils, injectors, evap purge, water temp etc most of it needs to be extended to be able to route wiring to fire wall instead of jumping over.
next to the alternator and PS accessory bracket runs wiring down the side of the engine - i pulled all that out of the main loom and routed it down from the ecm, it catches knock sensors, cam, crank, starter etc.
This is exactly what i was looking for, what do you suggest for supplies before i start? I see some buy many different color spools of wire to extend wires as needed, everything will be sottered and shrink wrapped
for covering everything loom in a few different sizes 1/4" - 1", high temp wire harness tape, ty-raps..... i "recycled" most of the wire i removed to extend a few things, the ground wire needs to be extended it does some weird splices in the harness. I would have liked to replace whatever wire i needed to extend, end to end, but that would have meant i needed to find the correct pins for ecm and connectors, and correct wire color. personally for my own vehicle i would be fine using a single color for anything that i touch, just so i know if i do have to trouble shoot something i can easily identify what i could have messed up. kind of a " because its my own" i will be the only person to ever touch it. if i did it for someone it would be different.
