ditto.. although, i just installed a apexi NEO a few weeks ago, and its really pretty easy to do.. took about 40 min to wire it in and get it set up.
Want a pita to wire? Go wire a megasquirt or the APEX-i electronic boost controller (this thing owns, though).
heh... you want a PITA.. i wired in a emanage with all the harness's into my tiburon when i boosted it.. the ECU was bolted to the firewall, behind the dash, and there was barely any room to access the harness.
give me a bit and ill spoon feed ya exactly what to do. i just gotta remember how i did the install, lol i used wire taps.. didn't bother with soldering.
alright, what exactly in the wiring diagram are you having issues with.. FYI, the only wire that actually HAS to be cut, is the MAP sensor wire, because one side has to read the output, then go thru the SAFC and output into the other side of the MAP wire so it goes.. MAP wire > SAFC MAP input > SAFC MAP output > MAP wire. ill try to get the colorings from the 'how to' to further explain that.. but the MAP wire is the only semi involved part of the install.. the rest can be done like the following. get the appropriate wire color on the PCM plug and put a wire tap around it. then what i usually do is strip about 1.5" of wire on the SAFC wire, fold it to double it up and twist it, then insert it in the wire tap and crimp it. i think theres only like 5 or 6 wires than need to be done that way. although, in the car we wired up, we didn't hook up the RPMs because he didnt have the tach module at the time.
i hate wiring also. but the SAFC in the SRT wasn't all too bad. ill be stopping by my buddys today and ill try to get you the harness wire that matchs with the PCM wires, then ill try to create an easier diagram of how to do it.
