Or... Doesn't one side of the HES tell the computer to fire the injectors? And the other side is the ignition...
You are correct, one for ignition the other for fuel. Since your HES is on the hit list to be changed if it is an old style, you would be ahead just to change it out.
While you are waiting for the HES to be returned from the rewiring, I would also pull the tank and remove the fuel pump assy and associated lines from the tank for inspection, I found that the U shaped hose on mine had a big crack in it, my bike had less than 24k at the time. Didn't think the break went completely through, but I was pretty happy to have found a protentional failure. May as well change the fuel filter while you are in there.
word of advise before you unbolt that plate, mark it in reference to it's location on the tank, makes it easier to get right orientation when trying to get it back into tank)
THIS right here ^ ^ ^ !!!!
Send off the HES harness for rewire and testing, work on in-tank stuff. Re-assemble with good HES and ride!
Don’t worry about “HAL”, auto correct does that.Has anyone shown how to build one of those HAL sensor things?

The top sensor controls the spark, the bottom controls the fuel pulse.
Don’t worry about “HAL”, auto correct does that.
GSAddict above has a great reputation for repairing/bring the wiring on a HES back to life.
OM
Wow.. sorry i did not write the question correctly at all...
.............................
Someone above gave me a really good idea... to just send out my existing HES and have it rewired, while I do the fuel pump.
I think that is a great idea... 'GSAddict' ..

while I am at it.. I will take the HES off and get it ready for GSAddict.

Before you loosen any of the screws that hold your HES plate to the bike, make scribe marks on the plate and the surround in at least two places. One on each side. After GSAddict repairs your HES wiring, you can put the plate back on the bike in the same position it was previously. Should not even need the timing box.
Was probably mentioned ... make index marks on fuel pump plate and tank and snap a pic to ensure proper alignment on re- install. Easy to go one hole either way . When cleaning up plate be careful to not lose that mark!
