Hey mate they are really easy to install, you just need to remove your cluster which is only a few bolts in and around it. Unplug the 3 plugs behind the cluster and remove it. once you have done that you will need to remove the small metal clips going around the perimetre of the clear plastic casing. Once you've done this there are about 5 plastic clips connecting the casing to the cluster which you need to undo, the clear cover should just pop off. As for placing the the glow gauges on you will be able to turn the tacho and speedo indicator to slide the gauge over it fuel and temp should be the same though you may have to remove the needle. as for the cables leading to them run them out the back of the cluster. The cables will be terminated with small plastic plugs so you may need to drill a small hole for them to run through or you can just cut them and hardwire them. If you do drill a hole make sure to not damage any circuitry. It's a pretty easy job if you need a hand with it just PM me
