Yes, thank you Al Gore for making all this possibleOriginally Posted by bareskier
I think the Delphi plugs are good, but they are a bit finicky and time consuming to put together. You also need some good specialty crimpers for these and they are a bit spendy. Due to the time consuming part, the last time I did this I switched over to Weatherpack. Weatherpack connectors are not as compact as the Delphi, but they are still high quality and easier to work with. I couldn't find an 8 position plug made by Weatherpack, so I went with (2) 4 position plugs. You still need a specialty crimper for weatherpack, but it's cheap and works good. Another thing regarding the Weatherpack, the design encourages better pin alignment and grips onto the pins better (at least in my opinion). Here's a quote from a post regarding this mod.

If you already purchased the Delphi plug, don't worry, its a great plug. You'll likely need a few extra pins to practice with though as these are easy to mess up when you're learning. If you haven't already got the crimper, then you may want to switch to the Weatherpack as you could buy the Weatherpack connectors and their crimper for less $$$ than the Delphi crimper alone. Both the Delphi and the Weatherpack connectors come with everything you need to seal the wires to the connector. It's all done with soft rubber. The Weatherpack has individual little rubber seals (one for each side of each wire, whereas the Delphi does it with one bigger seal (per side) with multiple holes. As for sealing on the injector side, I didn't worry about it. Mine are sealed as good as the original Toyota ones. On the last harness I built (the Weatherpack one) I was able to stretch the shrink tubing over the edge of the injector connectors and seal them to the harness by shrinking it down. Good luck and have fun with it. I enjoyed taking a break from the garage to do the harness. I commandeered the kitchen tableOne thing that always annoyed me with the van is the requirement to remove the top half of the intake manifold just to connect/disconnect the engine wire harness to the fuel injectors. The last time I did this I cut the injector part of the harness off & built a removable injector harness (it worked great). This makes it possible to completely assemble the engine before installation. I liked it so much I built a removable harness for this one too (old connectors were shot anyhow). I'm using Standard part #S697 Bosch style injector connectors w/wire and 4 PIN SQ 16-14 AWG Weatherpack connectors. I use 16 AWG automotive primary stranded wire to go from the injector connectors to the Weatherpack connectors. I solder & shrink tube the connections to each injector connector wire, then cover the assembled harness with more shrink tubing. Note: Special crimpers are required for the Weatherpack connectors. If you work with these type connectors (also used on GM) I highly recommend having a Delphi Packard Weatherpack Terminal Release Tool in case you need to pull pins back out. Here is the finished harness:
Male connector positions A&B power injector #1 & positions C&D power injector #2. Female connector positions D&C power injector #3 & positions B&A power injector #4.
. It was nice to sit down and work in a clean environment for a change. I had all my connector pieces, wire, shrink tubing, strippers, crimpers, and a heat gun all laid out in front of me. Tim
