R34 Gtt(with Rb26 Conversion)speedo/rev Problem..help!

[Clockworks]

Hi guys I wonder if anyone could help me,

We have fitted the engine,box and loom(inc pfc)from an R33 to my 98 R34 gtt

Its all gone well and the car is starting driving ok,where im having the problems

is with the speedo,rev clock,and water temp,Iv been told that simply connecting the relevent wires to the R33 ECU wont work....any ideas?,help/advice would be great.......

I also need help with the abs system should it connect up fairly easily to the R33 ECU?needless to say wiring is not my strong point........

sorry to drone on,one last thing,If I was to get the loom from an R34 Gtr would it be a simple plug and play affair

to get everything working?I know I would need a new ECU......

Thanks in advance.

Well, what's the actual problem? Does the tacho work, or not work? Is the speedo working? Is it accurate?

We're not mind readers.

my apologies to all, the tacho is not working at all,nor the speedo,im not sure where the r34 will get its signal from

the r33 pfc and if the r34 speedo will accept a signal. From the r33 box,once again all help and advice greatly appreciated. . .. . Thanks.

this is off the top off my head so i will check it later,

yellow red trace is tacho signal,water temp is yellow / black, speedo is yellow / blue all these wires are in the other white plug (with black cover and grey locking lever) near ecu plug,
