Here’s an easy one When converting a 4 to a 6 is it necessary to use six relay board. Thanks |

Nope
Actually it’s not always necessary to use one at all. |

I think Perry still does custom harnesses for whatever board or no-board you want to run:

Another option is to retain the -4 relay board / cover, if you're after more of an original look and you're swapping in a period correct 6 (requiring an external voltage regulator). Just need an engine harness to match up to the connector.

Not only does Perry build a great engine harness, he also explains it well. Plug and play.

no not at all and very very cost prohibitive.
I in my pamphlet 914-6 conversion guide or "what you are getting yourself into" have the wiring harness diagrams showing how to use the four board with a six engine QUOTE(sixaddict @ Dec 13 2022, 03:47 PM) Here’s an easy one When converting a 4 to a 6 is it necessary to use six relay board.

Typically not needed with a six and I removed mine.
From what I remember, what's on the board? 1. Fuel pump connection. With my 2.7 it was easier to wire up a separate fuse for the fuel pump. 3.2 and 3.6 fuel injection have separate connections for this anyway. 2. Heater fan relay. Not needed with a six conversion 3. Regulator. Most sixes already have a built in regulator 4. 914-4 Fuel injection. Not needed 5. ? Rear window defogger. Does yours have one? Either keep the board or rewire it. |
