After reading all the posts I could get my hands on concerning a transom mounted trim switch, I have ordered and received the Merc switch with GM style (Metri Pack) three cavity terminals. After looking to confirm what type of connectors I have, I found that they are the Four Winns style with the red lock tabs. I don't want to use crimp splices for fear of breaking/cutting wires during crimping and the chance of water getting into the spliced area regardless of how much tape or shrink wrap I put on the connections. I ordered Metri Pack connectors from pcsconnectors.com for a little over $6 for male/female connector, male/female terminals, wire locks and seals. Shipping was more than the cost of the connectors by about a dollar, but I figure $14 for a plug and play, water resistant/proof? connection is worth the peace of mind of corrosion taking out the trim system on the lake and making it easier to raise/lower the outdrive so I don't drag it again..... (it was just a little drag at slow speed...

)
I also bought a Irwin 3/4 inch auger bit for the installation of the switch. Not loking forward to breaching the hull, but I plan to put it in the same location that I saw on the FW website, on the transom to the left of the outdrive above the normal waterline, within arms reach when installing the drive supports for trailering. Will post pics when it is done.
