I got an SD kit for the 1990 I'm building, I have a 90 ecu, and might buy a tucked harness off someone it's a tucked engine harness with fuse box relocation and battery relocation, the works.. But it has no MAF connector since it too is setup for SD, but I don't think it ever was setup for e85..
I bought a 2g sd easy-harness from ecmtuning and a few 2g maf connectors and pins and stuff to convert my 1g maf connector.. So that stuff is kind of useless if I decide to buy this.
It's only 3 wires it should be easy enough, but all the insructions to install off ecmtuning wiki says..

If you're not running our SD cable, then the easiest option is to simply get the EFI Connection Part # 100-00741 pigtail and just wire it straight up yourself.
The ground connection needs to be run to chassis ground (i.e., do not use sensor ground off the TPS or MAF connector).
^^^(pretty self explanatory)
The power connection (labeled “Vcc”) needs to run to a switched +12v source. You can find a convenient switched +12v source on the MAF connector harness. This will be a thick red wire on pin 3 of a 1G MAF connector or pin 4 of a 2G/EVO3 MAF connector.
^^^(without the maf connector, where would I find an *IN*convenient switched +12v source? Hah..)
The signal wire (labeled “Out”) needs to run to the ECU's MAF input. This is pin 2 (green with blue stripe) on a 1G MAF connector or pin 3 (blue with yellow stripe) on a 2G/EVO3 MAF connector.
^^^(same.. No maf connector..)
.................
With that being said. Would I have to find the correct ecu pins and run the connectors wires all the way back to the certain ecu clip inputs? Or is there an easier way? I know there's only one way it can go in and I have to tap into that specific place.
If anyone can help I would appreciate it. If not I will try and contact ecmtuning and ask them.
