HELP! Need Subaru Tech: (Still have wrong harness.)
|
Warren Chapman
For prospective converters,
ONCE AGAIN, just can't stress enough the value of BEING SURE you can verify that all the required items are from the same vehicle: OTHERWISE KEEP LOOKING UNTIL YOU DO!! I bought my parts from a reputable and knowledgable salvage yard that stated they were very familiar with this conversion. Well... so far they've sent me two separate harnesses. The first one took me a few hours to figure out that it was wrong one. I found out later that not only was it the wrong one, but that only half of the harness was sent (there are two sections which connect together.) The second one came two weeks later, and I spent a whole week stripping and matching wires only to find out that the two main large (grey) plugs which connect to the harness on the engine do not match. Now what?? What else might not match?? Since the harness doesn't match the engine, is it possible that the computer might not either. To avoid future problems, should I start over from scratch with a whole new set (engine, harness, computer).... this time certain to come from the same vehicle. Can't proceed until I get some answers. Does anyone out there know: 1. Is there is any difference in computers from 90-94. 2. Do auto and manual shift cars have the same computer?? Is there a chance for a mismatch? 3. If neither 1. and 2. above matter, perhaps I can just get the correct plugs to match my engine and splice them in. Appreciate any feedback. Anyone know a good Subaru tech who could answer these questions. Warren C. |

Hobert will tell you (and did in the instructions) that the automatic subaru
harness is ok.? Most Subarus are automatic.? My wrecking yard
sent everything!? It included an additional controller box for the
a/t.? Following Hobert's culling instructions will leave you with
what you need and the remainder makes for impressive photos that will make
people think that you are both crazy and an electrical genius.

Wire colors could likely be different.? Both mine and Ron Bloomguist's harness had some wires with different colors and even had one or two wires going to different computer terminals than shown in Hobert's list. We even had some wire color differences between our harnesses and they are both 1991's. The wiring diagram, once again, saved the day. I will defer on the matching computer questions because I don't know.? You can ask the Subaru parts department what computer numbers are interchangeable. This problem surley won't require an entirely new set. Keep your engine or your wrecking yard will never talk to you again!. When you find out what year the harness is I suggest getting wiring diagrams for both the engine and harness, if different years, and sort it out.? The computer should govern because it needs the right wires in the correct slots.? In theory you could build your own harness from scratch by following the wiring diagram that goes with the computer. Splicing new engine plugs should not be a problem if you can get the plugs that match your engine.? You have to splice to shorten all the wires going to the plugs anyway so no big deal.? But you will have to, in the case of harness and engines from different vehicles,? trace the wires from your engine plug to where they go on the engine to make sure the corresponding wire on the harness plug matches in function. Ron Bloomquist traced all his engine plug wires to there sources on his engine while solving what turned out to be a minor problem.? He took a lot of time with this and made diagrams.?? When I did my harness, all my harness plug pins matched in function with Ron's drawings so I didn't trace the wires to the engine terminuses (if that is a real word). Good luck... It will work out!

yes there are differences and the Subaru techs have a book that details which computer will run with which air box etc. they will all plug in as normal I believe but not run properly you need the # off the comp. The wrecking yard you are using seems to be consistently reassuring people that A. we do these all the time b. have more experience in it c. and then sending the wrong parts out of different cars I know that was my experience as well as Rev. Brian in Orinda They are carrying on the tradition with yours. There is a subaru guru at a Bay area dealership and he is up on all this. Call me and I'll get you the number for Subaru Guru Jay 1985 Vubaru (farphrumleakin) ----- Original Message -----

We have not found a difference in the '90-94 computers except part numbers.

Since you have stripped down one harness, take it to a wrecking yard and find an engine harness that will plug to it, and try to buy just the little harness that is on the engine. You may need to loosen the intake manifold bolts to get the harness off the engine.
