HELP Wireing clean up

[scoggs01]

Im doin my first v8 s-series project it is a 95 sonoma and im wanting to clean up the extra wires what can i get rid of or is there a harness i can get i wanna make it nice it is gonna be a street truck i want heat and radio can i just cut all the fuel injection wires and things that i dont need. Thank erik

[Rickracer]

I'd suggest splitting open the harness, ear mark all the wires you'll need, then whack the rest. Save any of the ones that are switched ignition, they will come in handy for fan and fuel pump relays and such. :cool4:

[scoggs01]

Ok thanks for the advice i wasnt sure if it was a good idea to cut and wanted to be sure before i did any wacking lol.

at the mustang shop i work for we clean up engine bays all the time and re route harness in fender to make a no harness engine bay. most of thw time i completly remove the loom and tape from factory all the way bacl to firewall. from there i can cut or remove wire and then install new loom and tape to clean it up

[scoggs01]

by the way my peewee goes thru around 7200 in the 1/4 my gear is a 4.86 which is what i run , the 1/8 i have a 5.67 thats on motor

[scoggs01]

i read on another site that the whole harness on the driver side that goes to the fuse box comes out excpt a purple starter wire a pink coil wire and one wire for the altonator it this correct? Even tho i want all my lights and a radio.

Are you going to use the factory guages? If so there is maybe 5 wires that you will keep from the drivers side where it plugs into. A Haynes or chilton repair manual will have electrical wiring diagrams in the back of the book. It will tell you what the colors are and where they go.

hahaha..

[jdrags10]

If going to use factory gauges use the factory sending units. Say the oil pressure sending unit. Use the one for the year of your truck. That way it reads same pressure as the dash. Same with water temp. The senders read 0 to 90 ohms for examPle and your truch dash is calibrated for 5 to 30 ohms. So make sure to use senders for your truck.

ok thanks i went and got me a haynes manual to so that outta help is there any thing in the harness coming outta the pass. side by the fender

[jdrags10]

Almost all of the pass side will be gone. It was for the fuel injection.

[1fast10]

the wire harness in engine bay ends at the firewall with a large plug. if you strip all tape and loom back to this point you will see all wiring.you can trace the oil.water tep wires to the senders. you can also see what you need to delete.just for your info in this harness most of the heavy guage red are 12v battery. these will usally go straight to alt or battery. theheavy guage pink are ignition wires that usally turn on electronics. but the best thing i can tell you is invest in a chiltons book. it will have wiring schimatics and will show you what every harness and pin in the truck does.

yeah im gettin on that this mornin i talked to a gut on craigslist he said he would do all my wiring and hide it and run loom on what you cans see for 150 to 200 its a shop so im thinking of doing that but not sure ill decide after today whe i go do what you just told me. I bought a haynes book last night i dont understand them wiring diagrams i see the fuse and try to track it but i get lost ha ha. Thanks for the input im gonna try that now.

[scoggs01]

Im in the process of taking my dash out now i marked all the wires and where they plugged in to so would painless wiring replace all the harness if i went that route im gonna take all the heater vents and stuff out an put in a sheetmetal firewall while its out.

[Diabolical]

Post the process!! ;)

Take pictures and notes for later. Saves you time, and helps you remember what you did. Just a suggestion. Get the truck running, and then remove the uneeded wires. Just my 2 cents, easier to see what you may need for your swap. And then reloom everything to taylor fit your harness to the engine bay.

Good luck, and post your progess man.

I have alot of work to do before the engine goes in i wanna do a sheet metal firewall and take all wires i dont need out completely while dash is out thats why i was asking bout painless wiring.I know nothing bout wiring but i dont wanna cut wires and have bare ones I wanna take them out from the source.Any suggestions are welcome. Could i follow the AC control wires all the way back and remove them same way with fuel injection and everything else i want my radio, gauges, and all my lights for street driving. What wires should i keep handy for other elec. add on elec fans, elec fuel pump, ect. I have a few pics in my album of the truck had surgury so im at a stand still for two weeks it SUCKS!!!!!

[scoggs01]

I just got me a haywire kit awsome all wires marked easy to read instructions 100 bucks for everything
