I am trying to get my "plug and play" harness ready to plug and play haha, and have found a few diagrams and descriptions on wiring the factory tps correctly using the full range sensor.

This was posted by Claudio?


and this from bbc i think?

TPS side of plug / Mazda wiring harness side of plug / Haltech E6K 3-lead TPS wiring harness
BLUE BROWN/BLACK/BLUE BLACK (TPS Ground)
PINK BROWN/WHITE ORANGE (5VDC +ve)
YELLOW BLUE/GREEN/RED WHITE (Signal)

Claudio's diagram confuses me because the three wires coming from the long range tps going to the 6pin connector are RED, YELLOW, and BLUE.

BBC's description is a lot closer being that two of the three wires from the long range TPS are dead on and the last wire being red could depend on your perspective.

First I want to know for sure what to follow, since searching leads to different wire color combos and nobody once asking why these seem to conflict? Or maybe I am missing something?

Thanks

Yes I had the same exact issue and was able to get the wiring corrected. Got the info from BDC's write up.....PM'd

 

The left hand side of the document is correct.

G/R - TPS
Br/W - 5V
Br/B - Ground

 

I can see that, I was just concerned about the diagram showing the three wires coming directly off the full range TPS to the connector being Green/Red, Black/Red, and Green. When they are definitely RED, YELLOW and BLUE.

And since I don't have any of the factory harness those three wires where the only one's I was concerned with, not the other side of the connector.

Anyways I wired it as to per BDC's instructions after confirmation from RXnos1200 that directly to the S5 full range TPS is

TPS/Haltech

Blue -> Black
Red -> Orange
Yellow -> White

 

ANOTHER NOOB QUESTION

Ok so I don't really want to start another thread, so just hoping somebody sees this.

Just finishing up a few things, about to wire the fuel pump in.

I only have one of the orange wires, the other runs right from the relay back into the harness so I assume that is tied right to the battery 12v+ wire.

Checking voltage on the fuel pump 12v feed, after turning the key to on I get 12v+ for maybe two seconds and it drops back to 00.00 on the DMM, and I know that's dead wrong. I want to figure this out before I even bother wiring it.

Any insight?

Actually that is totally correct assuming you have the fuel pump prime time set to 2 seconds. The Haltech will turn the pump on to prime the system for a period a few seconds. Once it sees the engine spinning over, when you crank it to start it, it will turn the pump back on and keep it running as long as it sees a trigger signal. If the ECU doesn't see the engine turning over it will shut the pump off. This is a safety feature to keep the pump from continuing to push fuel in case of an accident.

You're using an S5 patch harness? You shouldn't need to do any wiring for the pump.

 

No patch harness just a flying lead.

But ok thats perfect then! I didn't realize that, I will continue wiring then. Thanks!

You mentioned the patch harness, could I just run the fuel pump supply to whatever wire on the stock ECU connector, or should I just run it the whole way directly to the pump?

 

I ran my wire directly off the 20A fused relay to the pump. figured it could use some rewiring since the car is getting up in age......

 

That's the proper way to do it IMO.

 

Yup, thats what I did, ended up firing her up tonight for a short time, so stoked!
