inSTalling THE PcH BOarD

The pyrometer that was installed will now have to be connected to the PCH Board, but first the PCH 

Board needs to be mounted in a secure location that both of the pyrometer ends can reach.

1. Gather all of the parts of the PCH Board assembly:

•PyrometerConnectionHeadwithPCHCable

•Self-tappingSheetMetalScrews

•Velcro

•Jumper

•ZipTies

2. The PCH Board needs to be mounted in a location 

that is secure (away from extreme heat and mov-

ing parts), and in a location in which the end of 

the Pyrometer Cable can easily reach. 

3. Use the sheet metal screws or Velcro, or both to 

securely attach the PCH Board to a safe location 

within the engine bay.

4. To connect the end of the Pyrometer Cable to the PCH Board, first remove the screw and nut on 

the end of the pyrometer leads, then remove the screws from the Pyro 1 heads on the PCH Board. 

Use those screws to secure the Pyrometer Cable leads to the PCH Pyro 1 heads, see the PCH As-

sembly Diagram (pg. 19) for a visual reference when connecting the pyrometer leads to the PCH 

Board.

notice: Do not remove the jumper from the Pyrometer 2 location unless you are  

installing a second pyrometer.

if connecting two pyrometers keep track of which location, Pyro 1 or 2, each 

pyrometer was attached to on the PcH Board 

5. Once the PCH Board is secure and the pyrometer is connected to the PCH Board, use zip ties to secure 

the pyrometer cables away from extreme heat and moving parts.

6. Run the end of the PCH Cable through the fire wall. It will need to be connected to the OBDII Adapter 

Plug. Use zip ties to secure all remaining cable left inside the engine bay.
