Here in a few days I will be installing an ISIS RB25 Intake Manifold [from RawBrokerage ] on my motor and I wanted to verify some things I've been finding on searches.

Below is the info I found on searches that makes things a little confusing.


Find 1

RB25DET TPS Wire --------------Q45 TPS Pigtail Wire
Red ----------------------------White
Yellow/Black --------------------Red/White
Black/Blue ----------------------Black/Yellow

Find 2

(Q45 TPS) to harness

(Red) to yellow/black
(white) to red/blue
(black) to black/blue


The Q45 TB I have has a red, black and white wire coming out of the TPS going to a connector. The TPS also has a connector built into the TPS.

Find 2 is an option that would work for me from what I can see,and this is what I need verified.

I would also like to know if there is anything else I should be aware of during the install.

below are photos of my TB, pretty sure its the right one. There's 1 TB plate and I know i have to remove the actuator thing

I just finished my install and have to route a few lines then wire up TPS as well. In fact, we both have RB S2s in 95s..


Also wanted to give you my email just in case you find something out, maybe you can relay info and I'll do the same.

I also have a question for you as well pertaining to the main vac line from the brake booster. I've searched but can't find a solid picture showing installation.
