Here is the other picture. On this picture is the far left top pin. Thanks.

I would push the connector out the back side and clean it up 1st.
then squeeze it a bit to make it fit tighter.

there's a little finger that snaps in when the connector is inserted into the plastic thingy.  you need to push that in, the the connector will slip out.

Thanks for responding Versy and Oldnslow. Can't wait to have all that fun taking the tank off again. I'll try Versy's solution first but will probably buy the connectors before getting started just in case I cannot get it to work. Thanks.

I used to be able to get in connectors with a straight pick and tighten up the connections, rather than pulling the wire out, but it never seems to last very long, I'd likely just go to the bullets, but then, I'm lazy  

You make a good point there Oldnslow. The headlight actually cut out on me on a country road where it was close to pitch black. I immediately pulled off the road, way off but before I could even think of what could be wrong it came back on and thank God it stayed on until I got home. Actually it cut out on me a couple more times but at least I was in well lit areas at the time. And of course it came back on before I could even think of what to do with it.

You might try cleaning the problematic terminal with Lysol Toilet Bowl Cleaner.  Put a drop or two into the terminal that is causing the problem, and let it work for a few minutes - but don't let it dry.  Then flush it out with water in a squirt bottle, and then some brake cleaner.....followed by blowing it out with your air compressor if you have one.  Then use a little dialectric grease on all the terminals to help prevent corrosion.

If that doesn't do it....the next step would be to take out the female end from the connector and see if it is deformed - you might be able to crimp it a bit tighter.

If you don't want to do any of those (or they don't work).....I have a Bullet Connector kit and can make you a connector to splice into the wiring harness to bypass that part of the connector.

Thanks for the additional input gentlemen. I actually considered what you described Stu, but I did not want to risk screwing it up further. I tried to get that wire out of the connector but did not have any luck and did not want to man handle it without having a ready alternative if I screwed it up. I scraped at it with a pick and tried to push it tighter and after all that I did add dielectric grease. And it actually works pretty well as long as I do not have to make a slow speed left turn.

Dave, I appreciate the offer for the pigtail but I need to get it done right away to make sure the bike is ready for heading to the Twisted Sisters next week. So, I'll be taking the gul durn tank off again and playing with it. Thanks.
