2 stupid Breva wiring harness questions...

I have a 2007 Breva V1100, on a recent road trip the high beam connector shorted out and fried the wiring harness. I bought a harness from ebay that was from a 2007 Breva V1100. The harness is identical to the original except that the ebay harness was missing the air intake temp thermistor. I opened up the loom expecting to find the broken wires and searched thru the wiring back to the right ECU connector but I found nothing. Is it possible that the factory installed a harness from a different bike in the ebay Breva? Also I have a 2 wire connector located behind the ECU and I don't know where it goes, any of yous guys have clue? TIA!

Hi Skin,

I believe that's the GPS power connector for the TomTom unit Guzzi was selling back in the day. Not much good now, since not even TomTom uses that connector anymore.

I've cut mine off and installed a standard SAE two prong connector to power a wireless charging phone mount.

Can't help you with the missing air temp wire tho.
 
The wires should be there somewhere. Look at the schematic in the downloads to help find them.
 
Sounds like your air temperature sensor has gone AWOL. Specifically, it connects to pins 9 & 18 (pink wire, brown wire respectively) on the ECU. Check where these wires run to.
 
Thanks again for the replies. I peeled back more of the harness and found the ends of the taped wires. The chop shop left all the other sensors connected to the harness but removed that one, smfh.
