Help: Diagrams for pyro and boost install
- Thread starter speedmetal6.6
- Start date
Here is how I do them
For the boost gauge, I drill and tap the intake elbow before the intake grid heater
Remove the black plastic intercooler pipe - Pictures of a LMM, but the plastic pipe is the same.
Then I drill and tap with a 1/8" NPT tap
Installed
Then clean out the inside of the intake piping to make sure there are no burs or shavings - Then reinstall the piping and install the boost fitting
Then for the pyrometer, drill and tap the passenger side manifold - Leave the motor idling during this process to blow the shavings out.
Then run the wires and boost tube up to the cowl and zip tie them along the cowl until you reach the other side. When you get there, run the wires down to the grommet below the brake booster and to the right (about 1 1/4" in diameter) and cut a slit big enough to fit your wires and boost tube through.
Then run wire up under the dash to the fuse box on the drivers side of the dash.
You then need to run the power, ground and light wires down the new pillar to the fuse box, and then grab the pyro lead wire and boost tube and run them up to the back of the corresponding gauges and attach.
Once you have your power wires combined, attach them to an add-a-circuit, and plug that into the SEO ACCY 10 amp fuse in the fuse box
And attach your ground to the stud that mounts the dash
Then you need to run your light wire to the brown wire with the white trace behind the dimmer switch, you will need a scotch lock and a male spade connector to connect the two light wires into
You will need to pull off the dash bezel to get to the dimmer switch, putting the shifter in low gear will assist you in getting the bezel off.
Once you get it off, you will need to pop the dimmer/light module out of the dash to access the dimmer wire
Test your gauges before buttoning everything up, and you should be good.

I used the Mid BEC to pull power and lights. I don't remember locations I used, but I like it better because I hate tapping into the stock wiring. I'll go take a look later to see what it was I used and try to get some pics.
I got a set of Auto Meter gauges that are LED. Is the wiring the same or will it be different? They didn't come with any wiring for power.
