Howdy all,
The swap so far is going fairly well. Slammed the transmission in last night and attached the cross member. Fired up the engine and it roared to life.
Now before I put the dash back together, I need to make sure that the "up shift" indicator which used to be the Overdrive indicator now functions properly for the newly installed M47 transmission.
Can someone please tell me or steer me in the right direction to finish this part up?
Thanks,
Matt

Are you installing the big tach in place of the clock?

I have the big tach from when it was an automagic. Now it will really make sense to have it.

I did this swap to my 91 about a year ago. I'll tell you my opinion, even though it's not really what you're asking for: Remove the bulb from that indicator in the cluster and forget about it, that's what I did.

If the dash is still out, is there a stray violet wire that terminates near the cluster but is not connected?
That would be the wire from 26 on the LH ECU which should replace the yellow/red wire from the OD relay at a connector before the cluster. Wire should be yellow red from connector to cluster.
From examining the wiring diagrams, I think that is all you need.
You might want to get a second opinion.

Don, I believe in my '93 I recall seeing the connector under the glove box. That is, the violet wire only goes to the glove box, then the yellow/red continues to the cluster from there. And depending on which tranny you have, one loose connector is taped up with that foam tape right there. I may be remembering it wrong.

Thanks, Sean.
The connector location was an assumption on my part and assumption in these matters is usually not a good idea. This somewhat contradicts a statement I made recently about not giving advice when I don't know what I'm talking about. But other than the location I believe I am the right track. If there is more to it than a simple wiring change I hope someone will explain it more thoroughly.
I appreciate the input.

Sean,
Took a quick glance last night and this morning, but did not see anything YET.
Was in a rush doing other things and got stuck with the clutch cable. What a pain in the rump. Still have not got it on yet.
In regards to the up shift light, do I still need to keep the OD relay in place or does that need to come out now?
Thanks,
Matt

Just noticed this.
You don't need the OD relay.

Bulletproof,
Thanks for the update. I found a wiring diagram that shows me that I need another relay and/or sensor plus something on the clutch pedal itself to make this work. Heading out to the PNP tomorrow to attempt to find these last remaining items.
Will let you know how it goes. So far so good. Nothing that I have not been able to overcome with LOTS of help from you guys here on the board.
Thanks again,
Matt

I'm not sure that you need that other stuff with the LH2.4 system.
I sort of alluded to this in my original response.
How old is the wiring diagram to which you refer? If it is pre '89, you might want to hold off.
I see the control unit and clutch pedal switch in the earlier diagrams but starting with '89 (first year for LH2.4) they are absent.
I'm still thinking this is just a matter of wiring.
If anyone knows, please explain.

Found it finally!
I found the VIOLET wire and buzzed it out to the connector. All I need now is the wire from the donor car and I'm in business.
Thanks for everything!

Is there no yellow/red wire that continues from the connector?

Bulletproof,
There is yellow/red at the cluster that currently sits where the violet one will now sit.
The yellow/red is for the OD and is no longer used. I've labeled everything that I know of so that if sometime down the road someone, not me, wants to convert it back they can. I'm heading to the local PNP tomorrow to grab two alternators and will then grab the violet wire out of one of the donor cars. Then I'll solder it and be done with the dash work.
Can't wait to put this to bed and get it back on the road.

This is how I understand it from looking at my own '89 w/ M47, corresponding with members of this forum and reading the official Volvo wiring diagram.
In the cars with M47 and upshift light the wire to the connector at the instrument cluster is yellow/red same as AT w/ overdrive.
The transition occurs at the connector. Manual w/upshift light is violet to connector and yellow/red from connector to 34 at instrument cluster.
AT w/ OD is yellow/red to connector and yellow/red (same wire used w/upshift light) from connector to 34 at instrument cluster.
Is the violet wire in your car actually long enough to reach the cluster?

According to the wire diagram for 1989, they list connector 34 twice. Once for the Manual transmission with VIO, and once for A/T OD with red/yellow.
The OD section is it own little component and does not go any where except to the shifter, OD relay, OD solenoid and then to the instrument cluster. There is not violet wire there at all.
My wire is about 5" long and I had to strip it to buzz it out back to the ECU connector to make sure it is correct.
Check your wiring diagrams again and you'll see what I'm talking about.

You are looking at that unsanctioned wiring diagram found at...I forget where. I have it and all of it's companion diagrams for other years.
They can be of some use but they do contain certain inaccuracies. For example, there are not two 34 terminals on the instrument cluster. There is only one. I also find them to be deficient in other ways.
I am not certain of the A/T OD relay location but if it is anywhere near the LH ECU I think you could connect the violet wire to the yellow/orange wire that previously ran between the relay and the cluster.
Your method will work, of course and I wouldn't discourage you from going forward. But I believe the cars were actually wired as I have described.

Bulletproof,
I went to the PNP yesterday and removed the wire from the donor car. It too was red/yellow just like in my car, except it went back to the wiring harness and was attached to the violet wire.
I soldered it to my violet wire and now I have the upshift indicator though I do not use it, it is there.

Mission accomplished.
I'm glad you got it done.
The shift light in my '89 also works but, like yourself, I don't pay much attention to it.
However, I don't subscribe to the notion that you will inevitably lug the engine if you shift when the light comes on. True, it is pretty useless on an incline but on a level stretch or decline it will improve fuel economy.

Bulletproof,
The year I was looking at was an 85 and mine is a 89, so I will hold off.
Should I go ahead and pull out the OD relay from under the dash?
Thanks in advance,
Matt

Well, it no longer serves a purpose so I would say, yes, remove it.

FWIW, the up shift indicator is near worthless. If you follow its recommendations, you will end up lugging the engine with every shift.

Understood, just thought it would be nice if it worked. Since it no longer will think that it is a slushomatic.
