Depending on how large the wire is you could route it to the drivers side and in by the the brake master cylinder. or you could remove the passenger side fender well guard and find the grommet that allows the ecu wires into the compartment. i would not suggest drilling a hole unless you are CERTAIN where it comes out on the other side. bad idea to drill into the ecu....

How to run a power cable from my 2000 300m batterie to the trunk for my amp

You normally have to drill a 1/2" hole depending on the size of your wire though the firewall and down the pillar then under the rocker panel by the bottom of the door (where you step in/out) and then on the side of the back seat to the trunk. Expect about 20-30min to run the wire. make sure you use a rubber/plastic gormmet on the firewall to keep the wire from shorting out and you need to fuse this wire off the battery. use the same amp fuse as your amp. (if 60 then use 60 at the battery)

1990 300zx non turbo has miss on 2 cylinders

dude, i think you have two spark plug cables cross over. go to your local autozone and find a "firing order" if it was a blown head gasket it would show on the compression test but i'm pretty sure its a spark plug cable cross over.

What did you wire the neon's to? Obviously whatever you wired it to overloaded the circuit and popped the fuses. Check you fuse box on the inside of the car. You should wire the neon's power directly to the battery. Don't forget the fuse shortly after the battery!

Alpine v12 amp no power

its your fuse box. i would bypass the fuse box and wire this amp directly to the battery via monster cable. make sure you attach a 30wieght fuse to the monster cable that is running from the battery to your amp. ground the amp against the trunk. scrape the paint of a section and drill a hole in the trunk. use this for the ground for you amp. this will fix the no power issue.

Firewall openings

ive always used the steering colum, just made a hole or went around the boot. look at the firwall for any rubber boots that have access to the inside and squeeze that wire in there. but if all else fails. you can run the wire under the car to the trunk. making sure to keep away from the pipes and using alot of ties to the frame or other. also you would have to drill hole in bottem of trunk then seal the left over room. write back if you have anymore questions, hope this helps.....

Problem with the clutch switch for '90 300zx

check your starter key switch on the steering column.
the contact for the starter is wired to the key selector.
you need the Factory Service Manual fot trace out the wire. In general, the starter wire is red, the current runs from the battery to the key switch then to starter motor.

If you have wired from stater to the battery directly, you are bypassing the key switch.
The clutch switch is mounted on the top side of the transmission near the converter housing. again, you need to located the FSM in order to figure out exactly where it is.
