Hello everbody

Today I install the VSL4200 on my 00 Jimmy but the problem is when I lock/unlock there is no horn beep anyone I install one and have same issue.

I buy it NOS for cheap price because no installation with it So, if anyone can find the installation or know how to solve this problem it will be helpful.

thank you

I solve the horn problem now I want to connect the wire that open the rear trunk glass but I don't know with which wire I should connect (Only one wire)
