I got an 8 pack of MSD 2400 connectors. These are the center type connectors that VW used on their old cars and Toyota used in 1987. I think it was $26 at Summit Racing. I bought a $20 crimping tool. I soldered the connections after crimping as it did not look at pretty as the factory crimp. I found if I bend over the insulated strain relief first then the electrical crimp looked better. I guess a fancier Molex crimper might be easier. Also if I had split the intake manifold so the electrical connectors were easier to reach, the project would have been easier but then I would have had to bolt everything back together. If you have ever worked on a 22RE you would know what I mean.
I guess if you are going to replace a bunch of connectors this is a fairly good deal. This also would have worked but a bit more expensive but would have looked more OEM. On the other hand the MSD connectors have easy pop off clips.
