It should be but remember the LA3 is programmed for the brown top injectors. The other thing is the LA3 is set up for an ACT sensor

Nope, You will have to add the wires for the ACT and then repin the coputer to swap the locations of the VAT and the ACT.

The early cars only used the VAT. The later cars(87-88) use the same pins for the VAT to go to the ACT and then they used new pins to go to the VAT.

On my wiring diagrams page you will find everything you need including a write up on it.
