What is the number on the top of the relay?

I received my Bosch TB yesterday and I realized the housing is thinner than the BRZ TB so I guess it'll need shorter bolts unless the Bosch TB to manifold adapter is thicker.

Also, series rule change came out yesterday which puts my car right on the limit for next year as it sits so no cams for me.

Somehow I failed to snap a pic of that. Here's one from their site that Irace posted.

Is it the same connector as the original connector in the kit? Would I be able to just rewire that connector?

Haven't got a chance to install yet. I think this just plugs into what we already have re-pinned. Will get it done this weekend at some point so I'll follow up when I do.

Did you already buy the cams?

I didn't, no. I was going to get Toda A3s and Toda valve springs from RHDJapan. I think the total was like $1100 delivered.

So far no go on the fuel pump relay. I've double checked my pin locations with what they provided and it just doesn't work. I can plug the original connector from the kit and get immediate power to the pump that stays on like before, but the relay doesn't get switched like it should with the newly provided setup. I tested the relay and it clicks over as it should but something isn't right. I'm at a loss so far as to what it could be if it's just supposed to be plug and play.

There are only two wires left that can be pinned. A light blue wire which I believe is what they want pinned and a white/black wire. Neither work.

Currently the relay is:

30 - Battery Pos
86 - Joined with Bat Pos using small red jumper wire
85 - Light blue wire from Fuel Pump Module
87 - Fuel pump Green

Black ground wire doesn't connect to the relay. It just connects Gray to Black like before. Kpower is closed so can't really troubleshoot much more until they can confirm there isn't some step they forgot to add into the instructions.

Welp, mine will be delivered today. I'll let you know if I have the same experience.

I’m assuming you guys emailed them, yes?

I haven't yet. I planned to call but they are closed on weekends. I figured before I messaged I should double check all fuses and relays associated with the circuits before wasting anyone's time. Since my car was originally an automatic, I've swapped the dash and engine bay harness over to a manual version. I'm worried that may contribute to the issue, but from looking over diagrams I don't think that's the case.


I'm also barely literate with wiring stuff, including relays so maybe there's something obvious I'm missing. Hopefully RedReplicant can confirm it should work and rule out it's a defectively wired part from Kpower.


Also to be clear I tested the relay outside of the car and harness to see if it would click adding power to the 30 pin and ground to 85. It clicks.

Confirmed, same issue as you.





I'll look through Haltech and see if there is some kind of setting that needs to be enabled.

edit: Not sure if it needs to change, fuel pump is set to digital switched with a fuel pump relay set to DPO 5 with a 5 second prime

edit2: Can't help but just laugh at this point

Is the pinout identical? Do you have pictures of the original connector?

I mention it because the writeup highlights five wires, and I feel like the original was only four wires. Was the grey used previously?

I totally didn’t drop the new connector somewhere in my car and lose it but they are the same except the blue wire gets pinned in too instead of it and the white/black just hanging.

The color coded plug they send/show is wrong.

The way the relay side is pinned has the blue wire next to the black wire, not the gray wire as indicated on the plug they provide. I moved the pin over on the pigtail side since I could easily do it outside of the car.

Still doesn't prime/run the pump.

Rotated to match perspective:
