Since I can't install my under drive pulley, I started looking at the mass air conversion info. I have all the parts and pieces but what pin do you use for the fuel pump relay powerand how is the best way to run the wire. Thanks
hm, on the coolcats page it only says
"You will also need to run a new wire to the fuel pump relay. In the Mustang, the fuel pump power wire gets its power from a different computer pin than our cars, so like it or not, you gotta do it. Of course, safety is the #1 priority here, so please be careful. Check the chart below for a reference."
but says nothing about on what pin to do it...
well i know when i did my maf coversion the kit from ford racing for the mustang, i did not change any wire just added the wiring for the maf, not sure why my runs but maybe u should try it before running the wire lol just to see if it works
Robert
ok someone chime in and tell me wy my car runs its been this way for awhile like 3 years now prolly cause when i ordered this the ford racing they mentioned the thermactor wiring but they said everything else was a dicect swap so i dunno i wanna her emore details on this thanks
The harness and the connectors for the MAF sensor and computer are from Ford Motor sport Performance Equipment. I am assuming, I just run the wire through the firewall plug it into the computer change theThermactor wires and I should be good to go
well yea but i did not even change the thermactor wiring cause thats not hooked up on mine
Not so, every EEC-IV wheather MAF or SD uses pin 22 to trigger the fuel pump relay. The MAF EECs do use a feed back circuit(pin 19) to tell the EEC that the F/P is receiving voltage. What happens if you don't connect it??? NUTHIN', the EEC sets code 89 in memory, and life goes on(in other words it will run just fine).
With the thermactor solinoids you should switch a couple of wires(EEC pins 11 & 51 with 32 & 38) so they will operate. If you arn't using solnoids then it doesn't make any difference.
think u Turbocoupe50 that clears up alot cause mine has that code in it but i never thought any thing of, u are the man
Robert
Thanks for the info TurboCoupe50. I moved the Thermactor pins and it works great.
Thank you TC five oh. I didnt do anything but I learned something today so it was not a wasted day!!!
Once I finish off my HO conversion, should i swap over to MAS Air???
IST makes a real good MAF conversion.
mass air kit (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7914956939&category=33553&sspagename=WD1V)
this kit would be all i need?? what about the Mas Air Sensor? would i have to get that from a junkyard or something?
Yes you would need a maf meter and a maf computer, could be sourced from a Mustang. Junkyard or ebay would probably be cheaper. :grinno: But this kit is all the wires you would need to convert your harness to mass air.
