do you want to replace with a new stock one if so there is a plug next o the firewall you unplug and then unbolt the coil like you are going to change the plugs. If you want to up grade or change it like I'm thinking about doing the dodge viper v10 uses 2 coils 1 with 4 post and 1 with 6 post and the use the same plug. the downside you have to buy 2 coils and you only use 1 of them and I haven't found out if it will work with the rest of the elec. and ign. system.it should but I would like to find one in a W.Y. so i save some money. now i did figer this out someone on here gave me the inf. but i don't remember who at this min. sorry.
