Found some of the white face gauges from a 2001-2004 Tacoma PreRunner in the junkyard. Will these gagues simply "Plug and Play" or will I need to take them apart and transfer the white backing to my original 4Runner Gauge cluster ? The visual differences between the two are minor, setup is nearly identical; tach/temp left, speed/fuel right. The only thing the Tacoma gauge cluster does not include is the gear position indicator[PRND2L] which is unnecessary anyway. Also some of the warning lights maybe alittle different but over all these two insturment panels are very similar. Going into a 2000 SR5 4Runner. Anyone have experience doing this swap? Thanks in advance!
