Ok, TD-81U is compatible with your head mechanically, but its from a OBD2 car(96-97 Del Sol VTEC). Your car is a OBD2B, so there may be a difference in the wiring between your cars harness(OBD2B) and the one on the distributor(OBD2).

The TC-08A is for the 2000 Integra GSR. The TD-84U is a distributor that was put on the older Integra GSR's. Sorry, but that was my fault in not asking what year your car was in the first place and giving you the TD-84U part number for the older tegs. The part number given to you by the dealer is correct and can be verified by this link: http://www.acuraoemparts.com/delray/...All&vinsrch=no (its part #1 in the list and diagram)

Sorry about the mix up...let us know how it goes!
