Hi I have a 1986 420 SEL with the stock Becker Grand Prix which has failed. I want to replace it with an inexpensive radio that works, and I do not want to cut the harness. Can you provide or recommend an adapter?

UPDATE: I ordered a simple Kenwood unit from Crutchfield, and they included a harness adaptor which plugs nicely into the factory main harness, and speaker plugs for these wires, so no cutting. My car is simpler as it does not have the additional amps; a + and - to the front and to the rear, via the fader on the center console. The only information I need now: the two female spade terminals on the factory harness: one is brown/blue stripe, and the other is solid blue. What does each of these do? I figure one triggers the antenna and one is something for the alarm system.
