just a quick question Rene.. or anyone that knows for that matter

do all turbo timers need a harness?
ie. the HKS one uses that tt3 one right? or can one simply splice into wires? :shrug:

You can splice the wires.
But the harness makes the installation easier, cleaner and much much faster.
It well worths $15.

For the HKS, yes, that is correct: the TT-3

Pretty much just plug and play with the harness. I have the HKS type. Just have to wire the ground and one to the hand brake.

Can this also work without a harness on the ST165?

yes it can, any turbo timer can be hardwired in. But why potentially damage 20yr old wiring when you can obtain a plug-n-play harness for around $20-30 usd?

not unless the turbo timer you have doesnt offer the harness for the 4th gen celicas, then you have no other choice.

I doubt very much we'd be able to find a harness for it so there'll be a bit of wire hacking going on!

Thank you :)

I just bought one of those A'PEXi pen style turbo timers with the air fuel ratio and whatever, i know u have to kinda splice wires and shit to get the air/fuel in. but can i just plug the normal part of the turbo timer straight in the back of my ECU. st185???
