    I am trying to find two items for a 1990 J body Lebaron convertible.

    One is called a timer relay and is part of the large relay center on the left side cowl. It will be on the end of the second row, the area actually protrudes a bit where it plugs in. Base configuration is that of a standard Bosch relay.

    The other is called a dimmer module and is located next to the fuse box, it will have a red 6 pin connector.

    I can't seem to find them shown in the parts list nor find much in the FSM on either item.

    Thanks.

    Is the timer relay to turn off the courtesy lamps after about 20 minutes?
    Is the dimmer module for the electronic instrument panel dimming?

    Yes sir, you are exactly correct as near as I can determine. If the timer module works like the older systems, it is more like 90 seconds.

    I remember my '96 Neon had a small timer circuit board inside a standard relay, in case someone left a door open so it wouldn't deplete the battery. It would time out after about 20 minutes.
    Doesn't your LeBaron have the dim-to-off (theater) courtesy lighting inside the BCM?

    I saw an illuminated entry relay (Mopar # 4318800) for Chrysler. Is this what you are looking for?
    1984 1991 Illuminated Entry Relay 4318800 NOS Chrysler New Yorker | eBay (at https://www.ebay.com/itm/1984-1991-Illuminated-Entry-Relay-4318800-NOS-Chrysler-New-Yorker/303131830728?hash=item469410a9c8:g:yo0AAOSw7tFcu3rW )

    The other timer I saw was for the concealed headlamp delay (Mopar # 4503024), but that isn't for the electronic cluster.

    The electronic cluster does use a different headlamp switch (for different dimming characteristics?) than a standard gauge cluster.
    If you have the old one, does it have a part number on it?

    IC, first, the relay you found looks like the one the 1985 and 1986 Lebaron convertibles came with. I am using a 1989 J body dash in the 1986 convertible, but recently obtained an almost complete wiring harness set from a 1990 Lebaron convertible. The "timer relay" is probably about the same internally, but plugs into a standard Bosch relay socket in the relay center (big block of up to 17 relays). It may have "theater" lighting in the BCM, but it is the base 1990 BCM for use with analog gauges. I found that the round socket parts of the rectangular black and red instrument cluster plugs will fit in the old round 11 pin plugs used on the 1989 analog cluster.

    On the dimming, I am aware of the differences, some had it in the BCM, some apparently in the dimming module as it takes the resistance from the headlight switch to adjust brightness. I have to use the 1989 headlight switch as the 1990 was a pod mounted one. I have added three small "reversing" relays to convert the 12V output of the headlight switch and 1989 column mounted headlight dimmer switch to a ground signal to the appropriate relays (Park Lamps, Low Headlamp and High Headlamp). The basic panel dimming for the orange wires is in the headlamp switch. I may be able to do a workaround on those and deal with the electronic dimming (the automatic dim when the headlights are on) may work once I get everything connected.

    The catalog I was using was the 1990 passenger car one:
    http://oskin.ru/pub/chrysler-dodge/manuals/Chrysler_Service_Parts_Catalog/CD2/82-96PassCar/90p.PDF
    I also looked ahead to 1992 93.
    J-body relays are in figure 8-100. Modules are shown in 8-300. Instrument cluster is 8A-1700.

    In the 1986 catalog was a 4186387 door lock illumination relay, that looks a lot like the 4318800:

    There is also the H-body 4221671 illuminated entry relay:
    NOS Genuine Mopar Entry Lights Relay 4221671. for 85-89 Dodge Lancer. for sale online | eBay (at https://www.ebay.com/p/1772769195 )

    The 1995+ Neon 'Smart dome lamp relay' is the conventional Bosch-style. I don't think it had the momentary delay when closing the door, but I remember it turning off the dome lamp if it felt that a door was left open too long. It is 5269787:

    I have those, downloaded them from TurboDodge.com when the links were shared there. Nothing seems to list it, I know I sent an hour one time several years ago trying to find a part, had the old one in my hand, poor parts guy was going crazy. I think I still have the 1986 one for the illuminated entry system and several of the 3 pin light delay ones. Maybe I will just have to see if I can make one of them work.

    Sometimes you need a mind reader to figure out where something is hidden in a parts list, Mercedes had a snubber mount for the front of the Diesel engine models, it was listed in the front suspension section.

    Thanks for trying!

    I will have to get the box of miscellaneous relays and look.

    No readable numbers, all the large ones are apparently underhood (starter, AC compressor and fan) I do have 3 of the small delay relays (3 pin) for the ignition lock light on the column, no numbers, just made in Haiti with US parts. The one on eBay you linked is what the 1989 and probably 1985 and 86 had, 5 pins with a timer built in. It mounted over the glove box.

    Ok, I found a PN for the dimmer module by looking at the 1991 parts list, 1990 must have been a year with a lot of running changes. The PN 4373858 and shows on the 1991 list as up to 2-20-91 then changes to 4672012. Still haven't found the "timer relay".

    IC, I did find the number for the older time delay relay (also 5 pins but a big rectangular can like the older starter and fan relays) it is 4339780, still no luck on the newer one.
