bolt it up and adjust it using the slotted bolt holes (turn clockwise or anti) you'll need a strobe to set it properly to 8 degrees iirc. firing order is 4231 iirc ? but might be totally wrong lol best bet is to go to a scrapyard and buy a haynes manual (few quid from there at most) thatll give you step by step instructions or find a cvh in the scrappy and check the leads on that
