Some help on behind the dash

I have removed the dash on my 1990 Mondial T in order to get at my A/C unit to replace the fan motor. However, looking at the wiring I noticed that a relay? was not connected and another relay? was hanging down and looked very much to have been a repair. The unconnected relay? has only "ITA IAMEC 370 and then 12V 88W (X2) DOT" marked on it. The three terminals are marked 49+, 49a, and 31-. Anybody know what this is and its assumed replacement, a "Hella TB 64 DOT"?

The associated relays were marked "acoustic" and are, I assume controllers for the various acoustic signals used. See photos.

Thanks much Steve. Mundane but nice to know.

 

Hey Jay, It is not difficult therefore that's why I am trying it. It is time consuming and you need to label everything. I have some pics and will post something. Not as good as Ernie but it will get the job done. It is a pita but it's relatively simple. I am going slow and double checking everything on my way. I have the dashboard out and the center console. It does look like it has not been fiddled with the exception of the flasher replacement above. I estimate that I have about 30 hours in it now and I do not have the heat/cool exchanger unit out yet. I had serious difficulty with things that I should not have had problems: the steering wheel would not budge, and the knee bumpers (only on the "T" as I understand) had mounting bolts that were almost impossible to reach. This was solved by leaving them on and removing the dash with them on (my bad). They are very heavy and makes the dash more difficult to manipulate but it's doable. The steering wheel was finally solved by talking to Verell. After stripping the threads on the steering wheel mount I used a gear puller unfortunately on the horn commutator ring mount (it dented the commutator ring in one place but its probably repairable; also NLA) and then placing a brass drift (punch) on the edge of the steering column while under pressure with the gear puller and giving it a hard hit with the antimony hammer so nicely supplied by American Hammer at the Mondipalooza! It exploded so to speak. So after I spent too much time on these two items the rest is just detail work which is even pleasant at times. So the saga continues. I will post something when I am more advanced. I expect more challenges when I get the heat/A/C exchange box out as I understand from Daniel that it was not made to be opened. We will see. Intrigue.

 

What are these? They do not seem to be mounted and are connected with plugs but are just laying there flopping around. Green bit srl is the company label but I do not know what they are. Thanks for your help.

Thanks Mike,

The observation that might make sense is that my "T" is an October build date and they apparently had already started to install them. Both of mine work fine I just should have remembered what they were. Daniel has them listed for $1127.87 each.

I also need to repair my statement above now that these ECU's have clearly been dismounted from their original mounting. I will take a closer look and see if I can return them to the original mounting. I speculate this was done to facilitate the radio installation.

Relax David. We can arrange an on-site consult; no problem! I am afraid the hard part is yet to come with the removal and opening of the heat exchange box! Did you just spray the contacts with contact cleaner to clean them?

 

Davis: My relay contacts were sparkling clean and the insides looked new. I put a tiny bit of Deoxit 5 on the contacts and reassembled.

 

You should remove the whole panel that includes the clock. There is a black plug which feeds all the switches and the clock in the console panel above and behind the radio. You need to possibly remove the radio? to disconnect the plug. There is a bulb which is the light source for the fiber optic lighting which needs to be disconnected along with the glass fiber optic cable which attaches to the top corners of the panel. Unhook those and remove the four 6mm? nuts around the periphery of the panel and it can be pulled out the front. All of this is a lot easier if you remove the radio. I did not remove the radio but I removed the center console which allowed even easier access. I hope this helps, David. It ain't easy. You can have your clock rebuilt from the specialist shop in California. Do a search here.

How are your seat belt ECU's installed? I think I must be missing something in my car. Do you have a rail or something to mount them on?

 

Nice find Tijn. Bought one. Been looking for cheap one for minimal use with 1/4 inch drive. Thanks much.
