Yes, OBD1 EEC V (oops addenda: should be EEC IV) per http://www.autoemf.com.au/ford_eec5.htm.
Made my own; just used micro spade connectors (they are called mini telephone spade crimp connectors in the Altronics Catalogue) a LED, a resistor and a piezo buzzer. Plus some heatshrink tubing as the pins arec lose together so it pays to cover the mini female spade connectors with heatshrink so you don't short two together. The good thing about the EEC V OBD socket is that there is a 12 V pin as well so you don't need to run a lead to the battery as suggested in the Gregory's manual. The same little LED circuit will allow you too test the ABS, Trans etc. It's a bit more fiddly to use that the engine bay set up of the earlier models and if someone knows of a source for a plug that will fit the socket things would be easier.
