Trough the firewall

[northsupra]

Ok i got alot of wires that' going into the engine bay and wondered how
you others have done it? I have allsow just seen the hole on the turbo side where the engine harness goes in to the ecu. Are there any other ways trough the firewall that i could use for my wiring.

Are there any way in on the driverside?
Becasue i have som gauges that's allsow needs a hole.

Make one. Or if you dont have AC/Heater you could go through those holes.

I drilled between/below the brake booster and clutch master cyl. Works well for me, hardly noticeable too.

Ditto.

i drilled down by the curved part of the firewall below the brake booster. It will come out by the steering column but high enough up not to be seen inside. It allows easy access from the engine bay and somewhat from inside.
I have two holes in this area for wires. Other way is to cut a circle hole in the large grommet of the engine harness to thread wires thru there. MY o2 wiring is there.

BE SURE to install a grommet into the hole you drill to keep the wire from getting rubbed by sheet metal. you can get grommets from the auto parts store or radio shack.

There is a wiring harness that runs from the driver's foot well through the fender and out near the fuse block in the engine bay. You will need to remove the plastic inner fender and the kick panel from the drivers side, but it is the cleanest way to route wires. My 1 gauge from the battery relocation follows this path.

^^^^
I say that as well.

 

[northsupra]

hole is drilled.... :boink:

 

[LuvMySilverSupra]

if u have an auto there is a hold for the clutch cylinder already, for 5 speed just drill down there and if u break something, u went too far.

 

[Idealsupra]

if you look right behind the intake manifold...if you want to go this far you can run the entire harness that way...just beware it requires a LOT of modification AND EVEN MORE work.

^^^^ awesome engine, and yea I have a 90 auto it has a small rubber hole in the driver side near the brake booster, I used it to run my venom 400, and my gauges still some room for additional hose or wires to be ran. already drilled just gotta punch out the rubber plug.

I just go thru the hole where the harness feeds for everything.
I tape the wires up to a vac line and pull them thru that way. makes life 10x easier
