TPI harness help

I am removing my tpi setup and there is a plug that is in the same harness but does not go to the ecm. Does anyone know what this one is for? Thanks in advance.
Im holding the male side of the white plug below.

If you want to retain your speedometer you can use this.c207 has the output to the iP iirc brown or grey.
The yellow wire at the ecm pin b10 is the vss 4k ppm input.

Not sure if you still have a automatic transmission, if you do you should look into this lockup kit.

No problem, the only other obstacle I think you need to look into is a fuel pressure regulator to drop the high pressure to run with a carb.
