I'm getting ready to install a SAFC-II in my car and have a question about the wire connections. Would it be best to solder the wires to the ecu harness or use wire taps? I've always heard solder adds resistance to wires and have always had good luck with wire taps. Opinions?

Soldering makes the best connections...never heard of it adding resistance.

I run a SAFC-2 in my DSM and I soldered mine into the ECU.  Just an idea for you Texas ... what I did was I went to a junkyard ahead and found a connector in a random car that had the same number of wires as my SAFC.  I believe it was a HVAC connector from a Subaru if I remember right.  Anyway, I cut my SAFC harness in half and soldered it in, that way it was essentially plug-n-play after I soldered it into the ECU harness.  I have pics somewhere if you want to see them.

Are you using only and SAFC or are you also incorporating a MAFT? If using the maf T have the output wire from the MAFT to the ecu go to the input wire to the SAFC. Then the SAFC output to the ecu.

With that combo I was able to really fine tune my MAFT setup.

Here's those pics Texas ..

And here's an up close of how I did it ... Like I said  above.  I just yanked the green connector out of a car in the junkyard.  The hardest part was keeping all the wiring colors straight b/c the SAFC wire colors didn't necessarily match the connector I pulled.  But if you make a little chart and your smart about it, it's not a problem.

Very nicely done, I really like that. By chance do you remember what car you got that connector out of? It looks like a Ford product.

It was like 10 years ago.  I think it was a Subaru HVAC connector right in the center of the dash near the radio - but I couldn't tell you what model or year - it was too long ago.  Although, Subies are all pretty similar.

When it cools down here in Texas I'll hit up the Pick-n-Pull and see what I can find. Thank you very much techboy.

Soldering is always the best option, any other type of connection will add resistance. Soldering becomes a molecular bond.
