Force 90 Spark Plug Wires

[Pittguy]

Hi,

Have been having fun with the 1700XR but felt some tuning up was necessary to improve things. One thing I feel I need for sure is new spark plug wires. On my 1989 or 90 motor I have the blue ignition coils (3 cylinder) where they go to the plugs.

My new guy question is before I make any attempt to pull the wire from coil pack is are they only an all in one part? Do I need to buy the three coil packs to get the wires changed? The coil pack at first glance does not open.

Thanks.
