I installed an older Gentex mirror in my 2006 Solstice, and found that I had to buy new connector pins to reliably make connections. Since I had to buy 100 of these, I obviously have plenty to share (gratis) with my fellow Kappa modders. The connector pins I bought are TE Connectivity/AMP 1123343-1 and are suitable for 20-24AWG stranded wires.
Send me a private message with your address and number needed, and I'll get you an envelope on the way.
