You dont really need the relay board but it can be handy. do yourself a favor and leave most of the wring under the hood intact and just run the MS wiring harness over to the where the SMEC / SBEB was. This way every wire you will need is in one convenient spot and if done properly will look completely stock. The fuel pump out on MS should be tied to the wire for the ASD relay. This saves a lot of wiring and ensures that if the motor stalls all the important thing get turned off (coil, fuel pump, injectors). I will be doing a MS1 3.0 install on my '89 Spirit at soon as I get rid of this pesky A604. Also replace your CTS sensor with a generic GM sensor. This way it will be plug an dplay with MS. The GM sensor will thread into your existing hole and utilize your existing connector and wiring.
