86 Wonder Wedge Posted September 23, 2014 Share Posted September 23, 2014 Trying to set-up a standalone box for this beautiful 85 orange digi dash, but have no idea what pins do what. The 90 and 89 FSMs do not help (as they have the analog and/or green digi dash hookups) and I do not want to kill this dash. Any help is greatly appreciated! 1 Quote Link to comment Share on other sites More sharing options...
BirdMobile Posted September 23, 2014 Share Posted September 23, 2014 I need this too. 1 Quote Link to comment Share on other sites More sharing options...
jono Posted September 23, 2014 Share Posted September 23, 2014 got a pic of what the stand alone box looks like and where it goes ? I may be able to start you off...... Quote Link to comment Share on other sites More sharing options...
86 Wonder Wedge Posted September 23, 2014 Author Share Posted September 23, 2014 Ah, this "standalone" box is just the enclosure I plan on housing it in along with the signal and DC generator to power the dash board. The back of the dash has a 17-pin clear plug, a 20-pin pigtail plug with a singular yellow wire and a singular red/white wire, then a combined black plug with separate 16-pin and 20-pin sections (both car-side plugs are separate, but will plug into the same socket on the board).

86 Wonder Wedge Posted September 26, 2014 Author Share Posted September 26, 2014 Even if a full dash harness diagram is not available, is there a possibility that some of these circuits run on 5V (like some modern dashboards)? I can see the smaller, 16/20 pin plugs being <12V as they are very small (similar to the ECU pins) but I don't recall there being a "signal box" in the digi dash setups (ref: my 86 XT). It just fed right from the sensors themselves. I also have Nippondenso's contact info for the USA. Think they could be any help? Quote Link to comment Share on other sites More sharing options...
Gloyale Posted September 26, 2014 Share Posted September 26, 2014 I will try to get some scans from the FSMs from 85/86... This is for regular EA82 body, correct? not XT? Quote Link to comment Share on other sites More sharing options...
BirdMobile Posted September 26, 2014 Share Posted September 26, 2014 (edited) I will try to get some scans from the FSMs from 85/86... This is for regular EA82 body, correct? not XT? Yes - Standard EA-82 station wagon GL or GL-10 body if you have it. Thank you! Edited September 26, 2014 by BirdMobile Quote Link to comment Share on other sites More sharing options...
Gloyale Posted September 26, 2014 Share Posted September 26, 2014 Yes - Standard EA-82 station wagon GL or GL-10 body if you have it. Thank you! Well.....to have a digi-dash it would have to be a GL-10. anyhow......I'll get the scans as soon as I can. 1 Quote Link to comment Share on other sites More sharing options...
Gloyale Posted September 26, 2014 Share Posted September 26, 2014 Here's the 86 diagrahms and testing info. ***note*** the pins and connectors shown on the first scan are the actual "at the dash" connections. The pins and connectors on the second scan that are actually labeled with wires location are the pins at the end of the "pigtails" used in the original setup. If you don't have these, you may need to source a set of the pigtails since there is no info on what's what actually at the back of the dash. I'm gonna go look now in the 85 FSM.....but it has notoriously lacking diagrahms and pics. Quote Link to comment Share on other sites More sharing options...

BirdMobile Posted September 27, 2014 Share Posted September 27, 2014 Thank you! Went to your image hosting site to download them. Are the air conditioner image scans from the same manual, or are those for something different? Quote Link to comment Share on other sites More sharing options...
Gloyale Posted September 27, 2014 Share Posted September 27, 2014 Thank you! Went to your image hosting site to download them. Are the air conditioner image scans from the same manual, or are those for something different? IDK There are TONS of different scans and pics from 9 years of USMB posting. They PROBABLY are EA82 A/C scans....I think from the 87 or 88 FSM? Quote Link to comment Share on other sites More sharing options...
BirdMobile Posted September 27, 2014 Share Posted September 27, 2014 One last question... Are the green and red digi-dashes the same pinouts and functionality? Quote Link to comment Share on other sites More sharing options...
Gloyale Posted September 28, 2014 Share Posted September 28, 2014 One last question... Are the green and red digi-dashes the same pinouts and functionality? Nope...totally different. red is 85/86..... Greens are 87/88...maybe some 89s? Quote Link to comment Share on other sites More sharing options...
86 Wonder Wedge Posted September 29, 2014 Author Share Posted September 29, 2014 (edited) These are perfect! Thanks Gloyale! and also a big thanks to jono for the email/scans. The other question I have is what sort of wave the VSS (A/D converter on the odometer) outputs and if it connect to pin 13 like the diagram seems to indicate or does it connect to the random Yellow or Red/White wires I have not associated with any of the plugs. EDIT: I do not have the "meter case" that the FSM talks about, where the odo and analog/digital converter assembly is located. I have just the digital cluster/microprocessor section of the dash. Is the VSS a square wave? (I would believe it is as what good would a triangle or sine wave be for a speedometer? And the ignition pulse signal (aka Tach) would be a square wave as well, yeah? I can grab these wave generators to produce the needed signals for increasing RPM and Speed read outs on the dash..

86 Wonder Wedge Posted September 29, 2014 Author Share Posted September 29, 2014 UPDATE: started a "build" thread for it and the ensuing stuff. http://www.ultimatesubaru.org/forum/topic/149279-standalone-8586-digital-dash/ Also, 89 Civic (DX) with EFI, ECU plugs (all 3) fit exactly for the black 16/20 pin connectors and the 20-pin white/clear connector in case you need replacements. 1 Quote Link to comment Share on other sites More sharing options...
jsyme Posted July 27, 2016 Share Posted July 27, 2016 Nope...totally different. red is 85/86..... Greens are 87/88...maybe some 89s? I have a 1989 GL wagon DL 5speed with a green dash USA Quote Link to comment Share on other sites More sharing options...
