Ken are these the most current versions?
Suggestion, a date or version number.
Thanks, very handy references.

There's a couple versions of these out there, but to my eyes, they were difficult to read, or lacked info, so I made these.

Green = sensor
Brown = ground
Black/Red = +12v
Purple = RPM signal
Notes:
-LH pin 15-
16V, 32V, inhibit decel inj. cutoff, is only implemented on green motherboards.
'86.5 LHs with yellow motherboards do not have this feature (missing components).
SAAB/Volvo with LH2.2 use this input to code for automatics.
-LH pin 19-
32V, LH octane loop, changes the O2 sensor loop rich/lean pattern slightly.
16V, Check Engine Light, indicates if the MAF signal is out of spec., LH in 'limp home' mode.
LH 2.2 LH22 LH2.2 ECU connector connectors terminal terminals pins pin plug S3 S2 85 86 86.5 ignition fuel injection

Ken,
DanglerB seemed to think that one of the pins powers the L/100Km gauge located on the Tachometer of an '84 Euro. Do you have any idea which one(s) to test? Would it pin 24 on the LH2 (16v)?
