converting ECM, need sugestions

I will be upgrading my 870 ECM to the later 165 ECM. I have the PROM burning equip and a couple spare memcals all setup with a ZIf socket and such.

My question is reguarding the splicing and pin technique.

On mike davis's page it looks like he used the type of splicing connectors that come with an MSD. You know those blue folding plastic pieces that use a tab of metal to cut through the insulation on both wires and connects them. Is this the best way or should I just strip the wires and solder them?

I bought some GM pins from the local electronics store, even though I'm not to sure if they will be needed yet. It looks like Mike Davis used shrink tube where the pin connects to the wire. I don't know if that needs to be done though. What about soldering the pins as well as crimping? That seems like a good technique although it appears GM just crimped them.


What is the best way to label the wires? I can imaging by function. But what about old/new pin location etc. by function is probably the best way, but maybe those experienced can shed some light.

Basically any advice is welcomed.

I just crimp at the ecm joint (on interior mounted ecms), all wiring splices are soldered, and heat shrinked.
