DOHC Swap TPS problems~

[Johannes]

Hi, I've got a problem with my harness.

I got my coupe with a dohc swap in it, it's an '89 and it's having RPM limitations problem (only goes up to 2,500 RPM). I was trying to look for the plug in or the wire that goes to the TPS but couldn't find it. (I'm using a DOHC harness from an S13 and I have S14 DOHC).

And so I thought they might've just cut it or something so I bought another S13 DOHC wiring harness, but the harness I got, it doesn't have the TPS plug-in on it so now the TPS isn't connected. My question is, where could it be? Is the S13 DOHC harness different if I try to connect it into an S14 DOHC?

I've also tried cleaning the MAF. And the TPS isn't connected at all.

Thank you in advance.
