Addendum...
One problem that you will encounter is with routing of the Tach and Econometer signals. On an 87 they connect to the engine harness via a pigtail connector near the DME connector. The 88 and later cars route those signals through C101. The best fix is to add the two pins to the body side of C101 (dealer parts) and re-wire the Tach and Econometer to the body side of C101.The car makes it possible, but the driver makes it happen.
