I have an 86 Vanagon with a 99 2.5 dohc engine that I purchased with a partial installation done but almost no other info on the conversion. Several of the group members have been very kind to E-mail me wiring diagrams and other info, which has helped me identify a number of the wires that are protruding from the partly installed harness. There are several, however that are still kicking my rear end. Coming out of the main harness are 2 smaller harnesses. One contains 1 large red wire, and 2 slightly smaller orange wires. These wires were originally labeled with paper tags, but the printing on them faded out while the van was parked outside sitting idle for a couple of years. Also, I don't know if these are original wires from the Subaru harness or if they were pieces of wire that were spliced into Subaru wires of a different colors. I have been able to partly read the tags on on the wires, and they are as follows: The tag on the red wire says RY
POWER. (battery power?). The tag on one orange wire says: HOT IN ART (hot in start?) and the other orange wire says IGNITION POWER. The second small harness contains another large red wire and a somewhat smaller black wire. The red wire says POWER and the black wire says A LAM.
SO - I'm guessing that the first red wire should have 12v at all times, the first orange wire should have 12v applied when the key is held in the crank position only, and the second orange wire should have 12v applied when the ignition is in the run position. As far as the red and black wires in the other harness, I don't have a guess as to what their application might be. I'm beginning to think that my best bet would be to just remove the harness and open it up to see what all was done inside. All opinions and suggestions will be greatly appreciated. !!

Darrel, See p. 60 here


The ECU gets continuous ignition 12V via the large red wire which is
connected to the hot post in the van distribution box, using an add-on
inline fuse. That would be the R wire coming from "MB-3 SBF-2" shown
on p. 60. The van's post is hot all the time, so I'm guess that's your
"large red wire".

The start signal to the ECU comes from "ST IGW" (LR) at the top of p.
60 and goes eventually to ECU 86 (RY). In the van, you provide that
the Ignition Start signal by connecting to plug T7a6 (RB) in the
distribution box. I would guess that your RY wire needs to be
connected to the RB wire of T7a6.

No idea about the orange wires.
