    Not sure if I'm posting this in the best place ... but what are the latest and greatest connectors being used for splicing the harness wires into the trucks headlight wires? Most concerned with water/salt/corrosion etc. Have had expensive problems with the cheap crimp-on connectors that Boss supplies.

    Not sure if you are talking about the wires for blinkers and running lights or not, but for those I always cut the end of the truck side harness, the I cut the running light and parking light wires and use heat.shrink butt connectors to tie it all back together. Have yet to have a issue on any of the trucks I have put plows on.

    Exactly what I meant, thanks. I remember seeing some new connectors for doing this and can't find them now. Don't remember where I saw them but thought it was here. I like the heatshrinks until there is 2 wires on one end but maybe I'm just paranoid now.

    Agreed, the butt connectors that have built in heat shrink.

    Thanks guys. You using the solder type or crimp?
    B&B, do you have to actually cut the wires in the truck to use these Solder Seal connectors also? You are using the similar style butt connectors also, correct?

    What guage connector are you guys using so you can stuff two wires in the one end?
    What guage wires are we dealing with?

    Anyone ever tried the Posi-Tap inline tap connectors? They look slick aside from the lack of a seal. I suppose they could be sealed with die-electric or silicone.

    I use crimp connectors, I'm a firm believer that a well done crimp is just as good as a soldered connector. Yes, you cut the wires for butt connectors. The wires are like 16ga, you'll have no problem using blue connectors. That is my most widely used size. The Posi-Tap connectors do look pretty slick, but I wont trust anything less than heatshrink for sealing.

    I use the solder style primarily when there's space to heat them properly, and when there isn't, rely on just the crimp type. But the most important aspect regardless is to use something adhesive lined and heat cured, whether it's Solderseals, a simple non-insulated butt connector with adhesive lined heat shrink, or simply adhesive lined crimp connectors. If the crimp is done properly the connection will only be compromised by corrosion so that is what you're after to prevent. And adhesive lined connectors or heat shrink fit the bill well.

    For joining three wires (yes you still cut the wire) the blue 14-16 gauge connectors work best as you're commonly joining wires in the 16-18 range in most cases. To tighten up the "loose" side where you only have a single wire, strip twice as much insulation off as you normally would and fold the wire strand over itself. This tightens up the space on the loose side of the connector making for a better crimp or solder joint.

    Personally speaking I avoid the Posi-Taps anywhere corrosion can be involved. They're ok in the passenger compartment but otherwise, no.
