Haltech TPS sensor bracket for REW TB (pics)
I could not for the life of me find anyone willing to part with a TPS pigtail for the stock REW TPS, and I've never once seen an FD in yard. A couple of guys mentioned finding the mystery plug in the wiring harness in a Geo Tracker, but I didn't have any luck. I decided to make my own bracket, and mount the Haltech supplied TPS onto my REW throttlebody. Here's what I came up with:
http://www.bfhracing.org/duck/tb1.jpg First I stripped the TB of all elements I found to be unnecessary including: The stock thermo switch and the thermostwitch actuator on the static arm The stock bellcrank, replaced with 1/2 of a TII bellcrank. (custom brass spacer) The (throttle trim?) dashpot and arm The stock TPS sensor, actuation arm, and baseplate http://www.bfhracing.org/duck/tb3.jpg I then gently filed the inside of the sensor to accomidate the larger bore and installed the sensor against the base of the throttle stop. The sensor is partially actuated in this configuration, most likely around 10-20% throttle which can be compensated for with the Haltech software. Sorry, that's the way it is. http://www.bfhracing.org/duck/tb2.jpg Here's the plate I made from stock aluminum. It's not laser perfect, nor is it terribly exciting to look at. I'll send my measurements to anyone who wants to try to make it. http://www.bfhracing.org/duck/tb4.jpg The sensor installed on the plate. http://www.bfhracing.org/duck/tb5.jpg Here is the whole thing in place. http://www.bfhracing.org/duck/tb6.jpg You can see I spaced out the plate with a couple of 1/4" nuts for time sake. I'll make a couple of spacers for it out of aluminum tube in the next couple of days. Note in the first picture you see one long screw, and one slightly shorter screw... These came from removing pieces of the TPS. The longer screw goes in the top. To mount the TPS, I used aluminum sheetmetal screws. I'm also likely to space out the TPS with a pair of small washers, as there is a small ridge between the plate and the sensor. |
Wow, that is really clean!

I have an extra tps pigtail. A little late though.

Why don't you use the stock TPS? That is what I use and it has been working for a few years now with no problems.

I would have sold you a stock TPS pigtail for 5$.
For parts like that contact JAP2LA |
Hate to pile it on but I also have a spare pigtail laying around :( Install looks clean though!
|
the same goes for me, but the TB had no tps to start with but the guy who send it to me has included a mean looking bracket with it anyway so i dont need to fab one up.

Looks good. Does it work? Does it have any slop between 0% Fault, 0%, and 1% when off-throttle?

Think Duck made two or three posts asking for pigtails and no one replied. Turns out 1st gen DSMs use the same style TPS so that's at least one more source for pigtails. |

Bumped it for a month, and no one had one for sale. It was holding up my build, so I improvised. |
