I plan on picking up another 92-99 bonnie in the next few months and I was wondering where people have done the wire.

I intend to run 3 amps drawing 150 amps of current or 2000watts.

For both my previous cars I drilled a hole in the upper part of the floor pan on the passenger side, but I feel that that will cause rust even though I put a groumet there..


I was wondering if anyone has put big wires in their car and where they drilled... :?:

Some drill a hole in the firewall...others drill partof the plastic where the wire harness goes through and use that.

by yours truly

I would like to show all how to pass a power wire through the firewall. I know that there is no pictures that show how to do a clean install with a 1/0 or a 2/0 wire. I know that people do not want to run the power wire over the STB and through the grommet, that makes the engine bay look like hell, I also know that people do not want to enter the door accordian tube.

so I investigated the engine bay and my FSM and found that there are only 3 places where there is a holein the fire wall, one is the Grommet on the drivers side and the other two are the main harnesses that run into the engine bay.

I ran my wire through the wire harness on the passenger side of the vehicle

remove the MaxiFuse relay center cover
locate the engine wire harness
remove the factory sealant to expose the plastic connector
remove the plastoc connecor with 7 mm bolts
drill a hole that is the size of your power wire





this is the most sensible position to run the wire. The factory wires are gluedto the plastic connector. you cannot remove these wires to get a power wire through there.

run the cable along the fender with the fuse, and have it rest on the coolant over flow bottle. The fuse has to be within 18 inches of the battery, the over flow bottle is a perfect spot for this


IN THE CAR. you will have to remove the glove box. there are 3 7mm bolts and then the glove box pulles right out. When the glove box is remove there is a alot of room in there. From the harness on the outside it is a direct shot here you can see where the power wire comes out at. this is looking towards the front of the vehicle



run the power wire away from the SIR and the PCM to avoid any problems

back to the outside:

make sure that you seal the off the area that the wire goes through with high quality sealant




take the factory sealant that is wrapped around the harness, and reapply it


finally reinstall the MaxiFuse relay center cover


and you have one clean install

It'* odd to me that you can see the air mix door actuator that easily. Most have a bracket there in the way. (Unless that'* only 96-99?)

i dont have a passenger air bag....that is why it looks so open and you can see it

96-99

another place it can be done...





a picture of it with the cover on will have to wait...can't find one at this second.

outstanding, thanks guys!


any ideas on how to fill the hole in my floorpan before I sell the car? just fill it up with silicone?

Silcone works wonders..or a round flat plug from autozone

they have those? Probably will check and do that then silicone it in place
