Ok, i have a 88 DX CRX with a Z6 motor already installed and working. I just wanted to know if i can swap the harness from the engine bay to the ECU with one from an Si so i can eliminate the messy DPFI to MPFI wiring. Do i need the whole fuse block and dash harness or can i just take the ECU side wiring alone. The fuse blocks are stamped differently with the harnesses SH2 SH3 and SH4. I am talking about 88-91 hondas. I wanted to take the harness from an Si car so i can have a normal looking engine bay instead of all this messy wiring from the DPFI MPFI swap. Any input is appreciated.
