I think there is a tech article somewhere on the site, to re-pin your current harness to use a speed density computer...... That would certainly be easier..

A lot easier than replacing a wiring harness.... I think there are less than a dozen wires that need to be moved...... Have a look here, before you decide.

No, the body connector is different as an '85 has a separate engine harness and car harness. A 89+ car has the engine and car harness together in the same loom.
