1983 300sd
 

i have searched but not found the info i needed. the p/o of my sd put in a kenwood tape player. when they wire it the hooked it up wrong and it doesnt keep its memory. i know that the yellow wire is the one thats supposed to keep the memory. my question is what color wire is the yellow one supposed to be hooked up to?
right now its hooked up to two black wires with yellow stipes on them. is this right? please help this is driving me insane. any info would be appreciated

also theres a connector with a red and a gray wire coming from it. could the grat one be the one i need to connect to?

nevermind i fixed it
