The protrusion on the top plug is at top right of the group of 4 wires, center plug=center right protrusion, bottom plug=bottom right protrusion.Īlso note that each plug will only fit in itâ€™s own socket, and only in the correct orientation. Notice that the semi-round protrusions are in different locations next to their respective group of 4 wires. So now the black wire (ground) is next to the top right protrusion, and the yellow wire (12volts) is to the left of the black wire. Notice the semi-round protrusions next to the connection diagram? Now look at the wiring plugs and note that they have matching semi-round protrusions. If you rotate the stamped diagram 180 degrees, it will match the plugs on the radio.

The stamp is correct, BUT is not meant to be taken as physically the same orientation as the plugs on the back of the radio. To remove a plug, depress the latch towards the wiring. You may have to remove the plug to see the small letters.

The plugs are marked right next to the wires with the letter code I posted earlier. Maybe someone else here has more experience with these radios and can advise you. One slip of the soldering iron and you are searching for another DM-98 audio module. You are dealing with sensitive I.C.â€™s in the audio here, and the usual precautions are in order be careful around IC connections. If your present speakers have one connection grounded, you will have to lift the ground connection.Ĥ: Service information only says 30BCMS1= â€œ1983 GM Corporate 2700 seriesâ€.ĥ: As long as you maintain the 10 ohm load for each speaker (voice coil).Ħ: Probably connect to the â€œtopâ€ of the volume control, as your present connection is. Speaker connections MUST NOT be grounded. I take no responsibility for any mistakes that may be in the service information.Ģ: As noted above, the dial lamp is connected to the cars light switch dimmer for the dash lights.ģ: Speakers are 10 ohm.

â€œJâ€ and â€œLâ€ are right rear speaker. â€œHâ€ and â€œKâ€ are Left rear speaker. â€œBâ€ and â€œDâ€ are left front speaker. â€œAâ€ and â€œCâ€ are for right front speaker. â€œMâ€ is dial light (goes to the dimmer for the dash lights). â€œFâ€ is 12 volt power to the radio, â€œGâ€ is ground. May be hard to see, but the connection plug has identifying letters by each connection. This is a much newer radio than the ones I work on, but here is the information from Delco Service bulletin 27D-1983-1.ġ: Delco service information for 30BCMS1 does not call out color of the wires. What would I do to add it to this radio? Photos are helpful.

I have instructions on how to add the iPod jack to my AM radio. I would connect LF and RF + and - to the dash speaker, correct?Ħ. I may replace my dash speaker with a dual voice coil speaker and then put a speaker in the rear arm rest panels. Trucks probably did not have woodgrain knobs.ĥ. Any guess what model GM vehicle it is from, and year? I am guessing 80s truck or maybe Caddy. I know I can connect two 4 ohm speakers in series and get 8 ohms.Ĥ. What ohm speakers are correct for this radio? My old speaker is 10 ohm. Is lamp for radio light? What would I connect it to?ģ. Won't use antenna because mine is not powered. 12 wires coming out of back include Lamp and Antenna. I would appreciate the wiring code if anyone knows it.Ģ. The two wires at the top,of the stack are yellow and black. Those wires are light blue and dark blue respectively. the wiring code is stamped on the case, but shows the ground and 12v as the two wires at the bottom of the stack of wires. Questions: please keep in mind that electrical and wiring is my downfall.ġ. Currently have the original AM with an iPod connection I added.
