Quick Question ON Wiring

[SilverLS]

Hey I know your looking at this Quick and i figure your the one i need to find wich wire the to hook up my a/f gauge i want to get it off the pcm correct because it will be more accurate instead of off on side or other of mainfold i have a 2002 v6 :Beer

Are you talking about where to hook your gauge into an 02 sensor line? If so, I would be very careful about that. Your 02 sensor works off of very minute voltages...typically between .1 and .9 volts. ANY resistance in that line can cause an issue with the ECM. In my opionion, it's always better to spend a few bucks and have another 02 sensor and bung installed. It's not that expensive and any muffler shop can weld a bung in for you.

Here's my install guide.......

A-Pillar Gauge Pod



I finally installed my A-Pillar and gauges last weekend.

I installed AutoMeter C2 Fuel Pressure and Air/Ratio gauges - can't have my NOS Pressure gauge or I do not pass tech inspection for my ESP class.

Here's some pics:

I tapped the fuel line between the valve and the fuel rail - nothing special.

I tapped the heated O2 sensor signal off pin28 of the middle PCM connector - pic below:

I then ran the wires from the pressure sensor and PCM tap through the PCM rubber seal in the firewall and the behind the dash (through a conduit) to the a-pillar.

I tapped the ground and dash lights off my white gauge face leads, tapped a 12v switched source from a lead in the steering column.

I was difficult getting the PCM out - pull the glove box out to get the rear bracing off - pull of the AC filter and ducting to get at the PCM connector.

ok thanks do i have to worry about the whole voltage thing that he was talking about and is the harness in the glove box or on the other side of the fire wall just want to know which way to go ?? thanks again

the harness is on the inside engine bay side.

the guages I used were meant to be tapped into the existing line - I have not had any issues yet (been about a year).

 

[SilverLS]

cool thanks again .....as far as being taped in line what do you mean??? also i have a anwser for your nitrous gauge problem all you need to do is get the electronic one that runs a transducer off the bottle and runs a signal wire to the front (gauge) its a little pricey thought looking about 180-220 so if you wanna have it that bad its out there. Let me know if you ever need anything for nitrous i work for a company here in florida called www.ny-trex.com check out the triple threat thats whats on my car and im working on the trunk this week and weekend got the box almost built and the two nitrous bottles are in primer just got to get a compressor and paint them up...later

it just a standard electrical tap - squeezed onto the wire and the allows a connector to tap.

I can't run NOS in my ESP class - period, tried to hide it but the guage gave me away.

The fuel pressure guage uses the remote sender - making it easy, only having to run wires through the firewall.
