Im good with soldering but I dont have any way or know how to heat shrink.

I did though pick up some varoius injector plug clips from A Saab, VW Jetta, and a Volvo.

Im just going to use what works and solder the crap out of it then buy a heat gun for heat shrinking.

parts store and harbor freight are just a couple of places that sell heat shrink tubing.

slip on before connecting the wires, solder, then move the tubing over the area, then use a lighter or heat gun to shrink the tubing.

Radio shack sells a bag of short pieces of heat shrink tube you can use or practice, and you can borrow a blow dryer if you have to, but the butane lighter works, if you are careful not to burn things. Practice and experience are what makes the prettiest solder & shrink jobs. Clean the wire up well (no black corrosion) before soldering, ad use a low wattage (25W) instead of the soldering gun. Put the shrink tube over the wire before soldering, and don't let the shrink get hot (you'll find out )
