Quoting: FUBAR
sorry ignore that, i'd still need 4 relays to have 1 Pin87 per Lamp...
Depends on how your doing it - you need a separate relay for Hi/Lo, so if going for '1' relay per lamp, you actually need 2 - therefore 8 in total. I would go for 4 relays, with each relay operating a pair. Whatever relay you use, you will need two feeds out from each relay. One way will have 1 wire out with you will run to 2 lamps, the other, using the above would use 2 leads out.
If I were doing it, I would do the following, using the 5 blade one above -
Pair as follows to a relay each
Both outer Lo
Both outer Hi
Both inner Lo
Both inner Hi
That way, if a single relay or fuse fails, you will still have light on both sides of the car operational, rather than both on one side going together.
