yes you splice, as that is your tps input. if you cut them you loose tps.

as far as using your defi stuff im not 100% sure on how to make it work.

w/c analog input do you suggest using for this pressure reading.

1 or 2 will work, iirc using #1 requires adding something to the ecu where analog2 requires removal of 2 resistors. im goot at taking stuff off of a board, not vice versa.

ok that's cool. So let me get this straight, you use pin b6 as your analog input, splice d20 and d22 and connect your wires from the sender to them and cut r2 and r3 am I correct? thank you.

yes green to b6, cut out r2r3, red and black get spliced to d20 22. red to 5v, black to ground.

b6 wire is cut from the harness too and leave the other end connected to the ecu.

IIRC b6 doesnt have a wire there. so you need to put green wire only to b6. then yes leave d20 22 there and add red to the 5v one and black to the other.

Cheers for sharing the knowledge, good to see some more techincal style posts here rather than the usuall how do connect my WB.

That is the exact same scale as the Autometer sender. I emailed Autometer about it, and they sent the info. I compared, and they are identical.

alot of aftermarket companies will use the same sensors. good to know for sure about the autometer since thats the 1 i am looking into purchasing.
