Creeper, the blue line shown on the 750x mother board is simply a short wire link between those two points. if this link is not made then the mod will not work and infact you may fin that the PSX will no longer boot any discs at all.

I remember from my days of modding that not all mod chips work with all versions of PSX. In fact if you ordered the chips before the 750x model was released then it may not function correctly anyway, if the 750x was arround at the time the there is a good chance that the chip will work fine as the codes are backwards compatable.

I you have any other questions then either post or email me direct.
