Digital to analog speedometer swap

[240bahamas]

Hello all,

I've seen topics on this before, but not the exact answer i've been lookin for so bare with me. My digital speedometer and HUD do not work in my USDM 1991 240sx. I've managed to get a hold of a JDM cluster from a S13 200sx. I'm assuming that this will plug right into the harness, if not let me know. Another thing, will the HUD still work with the analog cluster once connected? Thanks.
