Yello, quick question... thinkin of converting my DOHC ZC 88 EF back to the D15, but with multi-port EFI this time
It appears the the intake manifolds are different, distributors? sensors?
Should I try and find a SI engine harness? Or is the one I currently have set up for the ZC work just fine
Im probably over thinking this, limited time to do the "stock" conversion
just like to be prepared
thanks in advance

 

keep the engine harness you have - switch out the rectangular 5-wire plug for the distributor with a round 7-wire plug from an 88-91 MPFI harness - the extra 2-wires for the plug are the ones going to the CYL sensor on the end of the DOHC exhaust camshaft everything else plugs right in

 

If you need the round 7-wire plug, they are kind of hard to find in yards these days, but Monotech sold me a pigtail for about $10 when I did my MPFI swap.

 

Cool thanks for helping me clear that up!!Greatly appreciated!!!
