beans Posted April 23, 2009 Share Posted April 23, 2009 alright so i have myself an 86 gl wagon on my hands that i recently swapped and ej22 into from a 1993 legacy.. i have been driving it for a while and i have most of the problems worked out... knock on wood... anyway i am looking to clean up the wiring and get a couple things connected... i want to get the tach hooked up.. but looking at the cluster im not so sure where i would hook the wire from the ecu so some help there would be nice.. also there is an oil pressure gauge on the cluster and im not sure if i can hook anything to that but if i can i wouldnt mind doing it... also does anyone know if there is a conversion for the larger tires to know how fast you might be going.. any help on these things would be great.. thank much Link to comment Share on other sites More sharing options...
baccaruda Posted April 23, 2009 Share Posted April 23, 2009 Tach: Don't ask me, mine doesn't work either! My car has a digidash which I'll be swapping for an analog dash sometime this summer, which leads to... Oil Pressure Gauge: You have to get fancy with the oil pressure sender under the EJ's alternator. The EJ's stock OPS is an on/off which works fine for the EJ idiot light or my car's digidash's idiot light; an actual gauge (such as on your car an on the analog cluster I want to swap into mine) requires a gauge with variable output. There have been posts made about the OPS swap; you'll have to search. Keep in mind that the search doesn't work for words of three or fewer letters, like OIL Speedometer: There are products available that adapt the gear ratio and which I believe interface between the cable and the transmission. For now, I use the tire size calculator at http://www.miata.net/garage/tirecalc and have memorized how "off" my car's tires are at commonly encountered speeds.

backwoodsboy Posted April 23, 2009 Share Posted April 23, 2009 1986... Im assuming we're talking EA82? The swap I did was into an EA81 chassis, BUT I got the tach to work! You have to tap in somewhere to get a "tach signal" in order for the ECU to function. I tapped into the Fuel pump relay, and the tach signal ended up back-feeding to the tach! What a bonus!

Numbchux Posted April 27, 2009 Share Posted April 27, 2009 just thought I'd mention, that all EA82s have an oil light in the dash (on the left side of the column, in that strip under the cluster). it's only used on the DLs, but it's there on others. I wired the EJ sender into this....and it works great. it'd be nice to have a gauge, but my efforts to mount the EA sender to the EJ engine failed.....
