Lenny, I'm sorry to be the bearer of bad news. Unless there is something you are not showing, it looks like all you got was the adapter board for interfacing a (not included) megasquirt to the stock Ford wiring harness and the Megasquirt relay harness. In kit form together they run $142 You would still have to assemble the adapter board and source a case. In addition to this, you still need a Megasquirt ECU. I read the eBay listing and it clearly said it was a "Megasquirt for Ford". Either the seller didn't know any different, or he intentionally defrauded you. You be the judge. I checked his feedback as a seller. He didn't sell the Megasquirt separately within the last 4 years. SO, I'm guessing he doesn't know the difference.
I certainly hope I'm wrong.
If you are somewhat electrically inclined, all you need is the Megasquirt and adapt the donor's wiring harness. You don't need a relay board, relay board harness or any adapters. That is all I used. But you do have to know how to read a schematic how to solder and how to splice wires reliably.
•Uses your standard Ford Harness and connector.
•Designed to use the relay board cable on the connection from the Adaptor board DB37 to the MegaSquirt DB37.
•Larger connector holes, easier to assemble.
•TFI or EDIS pull-up resistor on board.
•New design PWM Idle driver on board. No MegaSquirt modifications required.
•Drivers for Fan and Nitrous relays.
•Input for Nitrous feedback or Table Switching.
•Knock sensor input.
•Proto area with +12V, +5V, and ground nearby. Allows you to add your own circuits. (EGT, VSS, ?)
•Optional 25pin connector for use with Transmission control..
•The Spare I/O Pass through connector J3 can be used optionally to run Wide Band signals, EEC or MegaSquirt signals in/out.
•Breakout connections for all EEC-IV connections.
•Cut points for European PATS ECU compatibility. (Fuel pump, SAW/SPOUT and PIP)
What you'll need to come up with--
A Ford EEC-IV ECU to harvest the case/connector from as per the MegaEFI documentation. This kit includes everything needed to enable the features above, with the only exception being the case and connector from a stock EEC-IV computer.
Click here to see our EEC-IV adapter board guide for full details of how to implement this system,including pinouts for 5.0 Mustangs and 2.3 Turbo cars.
So in short-- here's what you need:
•A MegaSquirt, I or II, either will work nicely
•MegaEFI EEC-IV Kit (this page)
•Stock Ford EEC-IV ECU (just to steal the connector and case from, it can be a dead ECU from a junkyard Taurus or most other 86-95 Fords)
