On a stock style L98 TPI setup the knock sensor screws into the lower driver's side skirt of the block in the water drain plug hole....wiring goes next to oil pan with a clip and goes up back edge of block...just one wire...

Re: Question for TPI guys - Knock sensor (Fevre)
There's a difference betweent he sensors for roller and non roller blocks. The roller ones are used in conjunction w/ an ESC that has an ignore circuitry for the valve train nosie (os it sin't picked up as knock)

Be aware that there can be problems when running roller rockers and headers. The knock sensor picks up the noise as detonation and retards timing.

I mounted mine in the clutch pivot ball location. Less chance of knock counts there. You will have to retap the hole 1/4"NPT.

Re: Question for TPI guys - Knock sensor (patsnitrovette)
I have headers and non-roller rockers, but my knock sensor is still too sensitive. I'm going to 1.6 rollers soon, and I think I might get rid of the knock sensor. Also, I've heard if you don't have roller lifters and you do have quite a bit of lift that the sensor will pick that up as a knock. Not sure how true that is.
