Roger, this is the crimp tool I use to get the proper, compact crimp to allow the pins to fit into the connector housing. Unfortunately, there isn't a brand name on the tool and I've had it for so long that CRS prevents me from remembering where I got it. I noticed the tool still has the white paint dots on the dies I used on my last wire job (I told you I had CRS ). I also have a ratcheting crimper that I use for Deustch connector pins (it has Volvo stamped on it). Summit sells a reasonable copy of an MSD ratcheting crimp tool that works very well. I believe it comes with dies to crimp spark plug wires, you will have to get the appropiate set of dies for the type of connector you're using separately.

Mike,
I saw a crimper like that for Molex pins at a custom shop this morning and his was from MAC Tools - very simple concept with the small point on one jaw that rolls the tabs into the center. I think for the few that I have to do I will do them manually. I am using a ratcheting crimper with multiple jaws like you reference - borrowed it from my son who wires airplanes and it works great.

For these small connectors (Molex type) what type of heat source is preferred to solder these d@#*ed pins? I generally use a Weller gun for bigger stuff, and the little iron I have for electronics is quite small to heat the pin metal. I need to find that second set of hands, Ken

Roger, I use a 40 watt iron with a needle or small spade tip. You can find the "helping hands" at Harbor Freight. The jumbo is $6.99 and the little one is $3.99

Those are both pretty neat, Ken. May have to run into town and pick one up just to have on hand - not much help under the dash, though...

Under the dash I'll use a test lead, a length of wire with alligator clips at the ends, and clip one on what I'm trying to solder and find some place to wrap the other end to keep it all stable.
