boost/afr gauge

[quiksilvia]

what did u guys find was the easiest way to wire a boost and/or air fuel ratio gauge. thanks

I don't really understand the question...power and ground for the light, signal for the sensor (or a vacuum line for a mechanical boost gauge.

As a side note, all A/F gauges that use the stock sensor are very close to useless.

thanks for all the help, what was the best way to run the wires, but i dont see a 240sx in your list of fun so i guess u cant really help too much

I can give you a generic answer

Look for a rubber grommet on the firewall, there's usually one around the steering shaft, and one around the brake pedal. Poke a hole in the rubber and run the wire through there.

Or you can put it in the rubber boot where your throttle cable comes through the firewall, thats what I did.

I did that. Downpipe had a lot of fun with those wires, even with header wrap on the downpipe, and aluminized heat barriers over the wires. Best bet would be to find somewhere further away from the downpipe. I'm thinking about adding a new grommet (making a new hole) on the passenger side... mostly as a "just in case" issue.

Using the throttle cable grommet is the easiest way, though......

i did that last night and just read the thread, thats cool. thanks guys

Mount them on the hood, old skool style, then u wont even need the firewall hassle... In fact, get some kind of monkey to sit in your engine bay and scream out temps and pressures, every 10 seconds. That'll be the best 10 bucks u'll ever spend on bananas. Sorry, can't keep it serious today. Must be that toga party residue from yesterday. Other people did provide valuable input, so I don't feel too bad.

You can hook the ground to the chassis near your SMJ. The power requires a switched power line with a 5A fuse, this is your radio power (red wire). The AFR's wire reads the o2 sensor. Look at your ecu wiring diagram or check the color of the wire that's going in through your firewall and hook it up near the ecu.

boost gauge basically the same, run a grommet through the firewall for the vacuum hose

its already done, but thanks `
