[Gr-Racing]

Well im working on bringing back to life a brick project i bought with no luck so far, change fuel pump and other minor stuff now im trying to get it to start with no luck.
Hoping you guys can help me out i check and have spark but the fuel pump is not working and the bike has a few wires unplug maybe you guys can tell more about these wires
Thanks for the help




Their is a brown wire that looks like it has a connection but wanted to ask before pluging also is the big wire harnes extra or connects to something.


Ps their is also a raw wire that was burn that im going to have to trace back cause i have no clue

The brown wires are generally grounds.  Not sure about the big plug, but if there is not a mate lying around it may have been to a radio.  Should be able to find a wiring diagram online.

I'd say the plug goes to the ignition module under the tank that sits under the wedge in the frame.

The plug is for a OEM alarm and immobilizer system.

You need to bridge contact 10 and 12 together (both is brown/red) to get the starter to function

You're starting from behind the 8-ball.  You have very non-standard wiring and connectors, lots of apparent modifications and additions and it's not a good sign when you have toasted wires.  There may be mayhem resulting from that incident going on inside the harness.  The brown wires terminating in 1/4" female and male spade connectors may be associated with the OEM alarm (can't say for sure having never seen an installed alarm) but they are non-standard for a stock K75.  I can see Scotchlok IDC connectors (which are bad news) that indicate PO additions. 


Start by tracing back that burnt wire.  If it disappears into the harness, then you'll probably have to start dismantling the harness to see where it goes and what collateral damage it has wreaked.  If you can discern an insulation colour code, then report it here and we can probably help identify what it is.

Thanks for all the help i follow the burn wire back and big surprise the wire is burn all the way to the ground under the tank also took that extra harness off i think it was for a radio or something but it was all a mess now i got 2 plugs left unused are they oem? one of them goose to another jack connect on the side






The one of the ground under the gas tank goose staright to the negative terminal of the battery?

The round white one is for an earlier version factory alarm than the harness you allready have removed,
the round black one is for other optional extras.

one of them goose to another jack connect on the side

That's a power jack for external accessories, or it can be used for connecting a battery tender.

Thanks for the help, one of the ground under the gas tank was ran straight to the negative side of the battery is that correct?

Non OEM, but a smart upgrade..........exept when/if you get welded starter relay contacts.
