PC III wiretap got disconnected

Last night I noticed my Power Commander III wiretap had come disconnected. So first of all the vampire clip thing sucks, and I know I need to solder it.

Even with the tap disconnected, my throttle works fine. The only difference (in the garage, have not gone out on it yet) is the throttle indicator lights on the PC donít go on.

I thought I would not have throttle issues if the tap was disconnected, or am I misunderstanding that?

Or does this mean the PC was never connected right in the first place?

Is the new map working if that wiretap is disconnected?

Background Info:
2005 919
PC III USB
Map uploaded and throttle calibrated
Installed it last year, and never had an issue
Engine stock other than flapper mod

Thanks in advance.

If the tap into the ECU was not connected, then no mapping calibration (well, adjustments) were being sent to the ECU.

PC might have had power, but it wasn't doing anything.

So it sounds like its normal that my throttle is still working, its just that I wont see that 20hp (kidding) gain from the PC3 while it is disconnected.

I have 0 experience soldering, but I'm otherwise reasonably handy and precise... will I be OK doing this on my own?

Yeah, soldering is a piece of cake, just watch a YouTube video.

Coat the wires in a bit of flux first so the solder sticks.
