Tpi with 0411 harness mods.

Searched high and low. Cant find any info on what modifications to the lsx harness aside for stand alone is needed to run tpi. Any help would greatly appreciated

How are you triggering the 0411? Converted vortec or 24x?

The info I have found you use vortec distributor as cam sensor only and efi connection 24x wheel with a vortec timing cover and sensor. But I cant find the harness info to make all that work

I wired my 24x system identical to a 2000 Chevy Pickup 5.3 liter. See attached .pdf

Nice thanks. I'm assuming I would use tpi:tps,iac vortec:distributor,cps. express van knock but don't know what year or engine and 5.3 everything else

There are several details I'm needing to know about your project to accurately say which parts to use.

The schematic I posted above is for Drive by Wire.

I think you actually need a Drive by Cable Schematic. see attached

Will be dbc. 2000 harness. Mild street 355 in a 91 5speed firebird. Was a v6 before. My tuned port setup is a 86 with 7165 ecm maf . Harness is showing it's age and rather not deal with the questionable maf's on eBay.

I used one Knock Sensor, Resonant.

I updated my 1999 S10 to a 5.7 liter Vortec / NV3500 to 24x / '0411, your upgrade will be similar.

I modified my original harness, using schematics from my local public library.

My original computer was already an underhood OBD2 computer. I basically added two cylinder to the old 4.3 harness, with the '0411 upgrade.
