I have loads of electrical issues. The high beam won't stay lit, I have to hold the light thingie pressed towards the steering wheel all the time. All the inner lights are out. I think it is the ECU Control Unit, marked Integrated Contl Unit 38600-SM4-S11-M1, S1 that is failing. I am trying to find a replacement. The closest thing I find on ebay is a 38600-SM4-G01-M1, G0. Can I use that woth my 1990 HONDA ACCORD IV Sedan (CB3, CB7) 2.0 i 16V (CB3) ?

 

Have you called a dealer? I know that part is an antique, but I cannot find the part number!
That seems crazy!

 

What makes you think it is the ECU unit?
