jono Posted December 1, 2018 Share Posted December 1, 2018 EA82 seemed to go their first optical distributor in 1987 with the XT. Was it only the turbo variant that got it in this year? In fact were there non turbo EA82 mpfi anything that got them in 1987? In our market in Oz the 1988 onwards EA82 mpfi got the optical distributor whether XT or Leone or L wagon ...touring wagon only I think. But these 88 onwards distributors gets a new part number. 22100AA410 for 1987 then 22100AA450 for ,88 onwards Not directly interchangeable it is said - unless swap two wires. But which two? Previously someone said swap green and white wire positions with each other Another has said black and white Now doubt second option as black wire connects to a male spade terminal in the distributor base at the module and this spade has a side bit that is connected to distributors body ie earth Not changing that ! Looking at distributors with no wires coming from base at all revealing 2+2 .male spade plug of optical module.... If module is same for the two part numbers they MUST be interchangeable without any wiring swap so long as all the wiring is retained right up to the white female spade 2+2 terminal that plugs into the module and held there by a screwed plate..surely ?? 1 Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 2, 2018 Share Posted December 2, 2018 Yes you have to swap two wires. I don't remember which ones. Ancient history for me now. GD Quote Link to comment Share on other sites More sharing options...
Steptoe Posted December 2, 2018 Share Posted December 2, 2018 If what GD recalls is correct and he has read my query to the detail I ask it would mean there are two different optical modules Quote Link to comment Share on other sites More sharing options...
Steptoe Posted December 2, 2018 Share Posted December 2, 2018 I would expect the wire swap does not involve the black as it is the earth,nor the red as it might likely be power Quote Link to comment Share on other sites More sharing options...
idosubaru Posted December 2, 2018 Share Posted December 2, 2018 Same here I did it a decade ago or something and don’t remember. But I think there’s a lot of threads for it. Could you find two wiring diagrams - one for each style, and compare the schematics? Quote Link to comment Share on other sites More sharing options...
jono Posted December 3, 2018 Author Share Posted December 3, 2018 working on the comparison - remotely - I have one set of manuals, then I got Greg the Guru with his set of manuals eh Greg the short wire run from rectangular white plug of females out of the base of the distributor to the round black connector may hold the differences Quote Link to comment Share on other sites More sharing options...
