zKars Posted June 10, 2010 Share #2 Posted June 10, 2010 There is a great thread on hybridz.org about wiring and the L28ET swap, its even specific to the 81 which is slightly unique to the 82/3. Search and yee will find. Good luck! Link to comment Share on other sites More sharing options...

sblake01 Posted June 18, 2010 Share #5 Posted June 18, 2010 The L28 ET uses a totally different and system than a 75. ECCS vs EFI. The wiring is different, the ECU is different, etc. You're going to have to do the research. Link to comment Share on other sites More sharing options...
