i have read somewhere that the ea2 engine / gearbox loom (and only ea2 as its the first of the 4 speeds and non smart lock) is a stand alone loom and then all you connect is the white 8 pin plug under the brake booster .... but i cant find any wiring diagrams or any other info on this method ,all wiring diagrams i have found start at eb2 on , nothing earlier, i have read panko;s thread ,and do like the way he has done the el computer to crossflow , but the same wiring will work with a 4litre ,then its the extra wires for the btr..............i have spoken to bill hooton about the barra computor and loom but he doesnt really like doing them and he is pretty much booked out for the next 6 months
